Concept explainers
(a)
Interpretation:
The given statement “for systems in a state of physical equilibrium, two opposite processes take place at equal rates” is true or false has to be indicated.
Concept Introduction:
Physical equilibrium is a state in which two physical processes which are opposing to each other takes place at the same rate at this moment there is no net macroscopic changes can be happened but system is dynamic and at equal rate the forward and reverse process are occurred.
(b)
Interpretation:
The given statement “a liquid-vapor equilibrium situation is an example of a physical equilibrium state” is true or false has to be indicated.

- . What does it mean to say that a state of chemical or physical equilibrium is dynamic?arrow_forwardConsider a cylinder containing a mixture of liquid carbon dioxide in equilibrium with gaseous carbon dioxide at an initial pressure of 65 atm and a temperature of 20 C. Sketch a plot depicting the change in the cylinder pressure with time as gaseous carbon dioxide is released at constant temperature.arrow_forward12.102 A chemical engineer is working to optimize the production of acrylonitrile to be used in the manufacture of carbon fibers. The reaction being used is the combination of propene gas, ammonia, and oxygen. The reaction is normally carried out at moderately high temperatures so all species are in the gas phase. (a) Write the equilibrium constant expression for this reaction. (b) The boiling point of acrylonitrile is 77 °C, and that of propene is -48 °C. What would the equilibrium expression be if this reaction were carried out at room temperature? (c) What characteristic of this reaction might cause the engineer to desire carrying out this reaction at room temperature?arrow_forward
- Tell what will happen to each equilibrium concentration in the following when the indicated stress is applied and a new equilibrium position is established. a. LiOH(s)+CO2(g)LiHCO3(s)+heat; CO2 is removed. b. 2NaHCO3(s)+heatNa2O(s)+2CO2(g)+H2O(g); The system is cooled. c. CaCO3(s)+heatCaO(s)+CO2(g); The system is cooled.arrow_forward. For the reaction system C(s)+H2O(g)H2(g)+CO(g)which has already reached a state of equilibrium, predict the effect that each of the following changes will have on the position of the equilibrium. Tell whether the equilibrium will shift to the right, will shift to the left, or will not be affected. a. The pressure of hydrogen is increased by injecting an additional mole of hydrogen gas into the reaction vessel. b. Carbon monoxide gas is removed as it forms by use of a chemical absorbent or “scrubber.” c. An additional amount of solid carbon is added to the reaction vessel.arrow_forwardConsider the following equilibrium system. N2(g)+O2(g)2NO(g) a. Write the chemical equation for the forward reaction. b. Write the chemical equation for the reverse reaction.arrow_forward
- 5.2. What is the difference between a static equilibrium and a dynamic equilibrium? Give examples difference from the examples in the text. What is similar for the two types of equilibria?arrow_forwardA 4.72-g sample of methanol (CH3OH) was placed in an otherwise empty 1.00-L flask and heated to 250.C to vaporize the methanol. Over time, the methanol vapor decomposed by the following reaction: CH3OH(g)CO(g)+2H2(g) After the system has reached equilibrium, a tiny hole is drilled in the side of the flask allowing gaseous compounds to effuse out of the flask. Measurements of the effusing gas show that it contains 33.0 times as much H2(g) as CH3OH(g). Calculate K for this reaction at 250.C.arrow_forwardGiven the reaction: 2CO(g)+O2(g)2CO2(g) When there is an increase in pressure to the system one would expect: a. an increase in the amount of carbon dioxide. b. an increase in the amount of carbon monoxide and oxygen. c. a decrease in the amount of carbon dioxide. d. no change in the system.arrow_forward
- Indicate whether or not each of the following changes would affect the value of a systems equilibrium constant. a. Addition of a product to the equilibrium mixture b. Increase in the systems total pressure c. Increase in the systems temperature d. Addition of both a reactant and a product to the equilibrium mixturearrow_forwardThe equilibrium constant expression for a given reaction depends on how the equilibrium equation is written. Explain the meaning of that statement. You may, if you wish, use the equilibrium equation N2(g)+3H2(g)2NH3(g) to illustrate your explanation.arrow_forwardIndicate whether or not each of the following changes would affect the value of a systems equilibrium constant. a. Removal of a reactant from the equilibrium mixture b. Decrease in the systems total pressure c. Decrease in the systems temperature d. Addition of a catalyst to the equilibrium mixturearrow_forward
