EBK INTRODUCTION TO CHEMISTRY
- The boxes shown below represent a set of initial conditions for the reaction: Draw a quantitative molecular picture that shows what this system looks like after the reactants are mixed in one of the boxes and the system reaches equilibrium. Support your answer with calculations. Consider an equilibrium mixture of four chemicals (A, B, C, and D, all gases) reacting in a closed flask according to the foll owing equation: A+BC+D a. You add more A to the flask. How does the concentration of each chemical compare to its original concentration after equilibrium is re-established? Justify your answer. b. You have the original set-up at equilibrium, and add more D to the flask. How does the concentration of each chemical compare to its original concentration after equilibrium is re-established? Justify your answer.arrow_forward. Consider the exothermic reaction CO(g)+2H2(g)CH3OH(l)Predict three changes that could be made to the system that would decrease the yield of product over that produced by a system in which no change was made.arrow_forwardQuestion 57 and 58: In Chapter 9, we discussed how to identify major and minor species and how to write net ionic equations. These skills are based on the solubility of ionic compounds, the strengths of acids, and the stability of certain ion combinations. Use these ideas to predict the favored direction of each equilibrium given. In each case, state whether you expect the equilibrium concentration to be large or small. a. HCl(aq)H+(aq)+Cl(aq) b BaSO4(s)Ba2+(aq)+SO42(aq)arrow_forward
- The boxes shown below represent a set of initial conditions for the reaction: Draw a quantitative molecular picture that shows what this system looks like after the reactants are mixed in one of the boxes and the system reaches equilibrium. Support your answer with calculations.arrow_forward. Before two molecules can react, chemists envision that the molecules must first collide with one another. Is collision among molecules the only consideration for the molecules to react with one another?arrow_forward. Explain what it means that a reaction has reached a state of chemical equilibrium. Explain why equilibrium is a dynamic state: Does a reaction really “stop” when the system reaches a state of equilibrium? Explain why, once a chemical system has reached equilibrium, the concentrations of all reactants remain constant with time. Why does this constancy of concentration not contradict our picture of equilibrium as being dynamic? What happens to the rates of the forward and reverse reactions as a system proceeds to equilibrium from a starting point where only reactants are present?arrow_forward
- The gaseous reaction 2HBr(g)H2(g)+Br2(g) is endothermic. Tell which direction the equilibrium will shift for each of the following: a.Some H2 is added. b.The temperature is increased. c.Some Br2 is removed. d.A catalyst is added. e.Some HBr is removed. f.The temperature is decreased, and some HBr is removed.arrow_forwardConsider the following equilibrium system. N2(g)+3H2(g)2NH3(g) a. Write the chemical equation for the forward reaction. b. Write the chemical equation for the reverse reaction.arrow_forward. For the reaction system P4(s)+6F2(g)4PF3(g)which has already reached a state of equilibrium, predict the effect that each of the following changes will have on the posit ion of the equilibrium. Tell whether the equilibrium will shift to the right, will shift to the left, or will not be affected. a. Fluorine gas is removed from the system. b. Phosphorus is removed from the system. c. Phosphorus trifluoride is removed from the system.arrow_forward
- Consider 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_forwardWhat happens to the reactants in an ineffective molecular collision?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_forward
