Chapter 12, Problem 6QRT

Indicate whether each statement below is true or false. If a statement is false, rewrite it to produce a closely related statement that is true.

1. (a) For a given reaction, the magnitude of the equilibrium constant is independent of temperature.
2. (b) If there is an increase in entropy and a decrease in enthalpy when reactants in their standard states are converted to products in their standard states, the equilibrium constant for the reaction must be negative.
3. (c) The equilibrium constant for the reverse of a reaction is the reciprocal of the equilibrium constant for the reaction itself.
4. (d) For the reaction

   H₂O₂(ℓ) ⇌ H₂O(ℓ) + $\frac{1}{2}$O₂(g)

   the equilibrium constant is one half the magnitude of the equilibrium constant for the reaction

   2 H₂O₂(ℓ) ⇌ 2H₂O(ℓ) + O₂(g)
