is a substance that increases the rate of reaction but has no effect on the equilibrium composition of a reaction mixture. A Moving to another question will save this response.
Decide whether each of the following statements is true or false. If false, change the wording of the statement to make it true. a) The magnitude of the equilibrium constant is always independent of temperature. b) When two chemical equations are added to give a net equation, the equilibrium constant for the net equation is the product of the equilibrium constants of the summed equations. c) The equilibrium constant for a reaction has the same value as K for the reverse reaction. d) Only the concentration of CO2 appears in the equilibrium expression for the reaction: CaCO3 (s) ↔ CaO (s) + CO2 (g). e) For the reaction CaCO3 (s) ↔ CaO (s) + CO2 (g), the value of K is numerically the same whether the amount of CO2 is expressed as molarity or as gas pressure.

What would happen to the equilibrium position (shift to the reactants, shift to the products or no shift) if: a. The pressure of the system was reduced. b. The system was cooled down. c. The partial pressure of H2S was reduced. d. More CS2 was added to the system.
Chapter 1 question 6: Ammonia has been studied as an alternative "clean" fuel for internal combustion engines, since its reaction with oxygen produces only nitrogen and water vapor, and in the liquid form it is easily transported. An industrial chemist studying this reaction fills a 50.0L tank with 4.6 mol of ammonia gas and 4.5 mol of oxygen gas, and when the mixture has come to equilibrium measures the amount of nitrogen gas to be 1.2 mol. Calculate the concentration equilibrium constant for the combustion of ammonia at the final temperature of the mixture. Round your answer to 2 significant digits.
i See Periodic Table See Hin Increasing the concentration of a reactant shifts the position of chemical equilibrium towards formation of more products. What effect does adding a reactant have on the rates of the forward and reverse reactions? Choose one: O There is no effect on the forward and reverse reactions. For an equilibrium reaction, the forward and reverse rates are always equal. O Both the forward and reverse reactions speed up by the same amount. O The forward reaction speeds up immediately. As more product is made, the reverse reaction starts to speed up as the forward reaction starts to slow down until they are equal. O The forward reaction slows down initially. As the reaction proceeds, the reverse reaction slows down to meet the new forward reaction. O The forward reaction speeds up. Eventually, production of the product speeds up the reverse reaction rate to match the new forward rate. O It is impossible to say without more specific information.
Equilibrium is reached in a chemical reaction when A. the reactants are completely consumed. B. the concentrations of all reactants and products become equal. C. the rates of the opposing reactions become equal. D. the forward and reverse reactions stop.

Explain Equilibrium criterion for a chemical reaction that takes place adiabatically?
When a reaction's reaction quotient is smaller than its equilibrium constant, what does this indicate about the reaction's equilibrium? The reaction must proceed in the reverse direction to return to equilibrium. The reaction is at equilibrium and will not change. O The reaction must proceed in the forward direction to return to equilibrium. O Nothing. There is no relationship between the reaction quotient and equilibrium constant.
