Chapter 15, Problem 69SCQ

Decide whether each of the following statements is true or false. If false, change the wording to make it true.

1. (a) The magnitude of the equilibrium constant is always independent of temperature.
2. (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.
3. (c) The equilibrium constant for a reaction has the same value as K for the reverse reaction.
4. (d) Only the concentration of CO₂ appears in the equilibrium constant expression for the reaction CaCO₃(s) ⇄ CaO(s) + CO₂(g).
5. (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 moles/liter or as gas pressure.
