The equilibrium constant of a system, K, can be related to the standard free energy change, AG using the following equation: AG = -RT In K where T is a specified temperature in kolvins (usually 298 K) and R is equal to 8.314 J/(K-mol). Under conditions other than standard state, the following equation applies AG=AG" + RT In Q In this equation, Q is the reaction quotient and is defined the same manner as K except that the concentrations or pressures used are not necessarily the equilibrium values.

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. For a given reaction, the magnitude of the equilibrium constant is independent of temperature. 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. The equilibrium constant for the reverse of a reaction is the reciprocal of the equilibrium constant for the reaction itself.
