Problem
A straight-line plot of ln K versus 1/T for a gas-phase reaction has a positive slope. If the temperature of an equilibrium mixture of this reaction is raised from 300 K to 350 K, which statement best predicts the change in the amount of products present at equilibrium?
(a) The amount of products will increase because K becomes larger at the higher temperature.
(b) The amount of products will remain unchanged because Q equals K at all temperatures.
(c) The amount of products will decrease because K becomes smaller at the higher temperature.
(d) The change in product amount cannot be predicted without the initial concentrations.
