Pick out the wrong statement. A. The conversion for a gas phase reaction increases with decrease in pressure, if there is an increase in volume accompanying the reaction________________?
Correct answer: B. With increase in temperature, the equilibrium constant increases for an exothermic reaction
- A. The equilibrium constant of a reaction depends upon temperature only
- B. With increase in temperature, the equilibrium constant increases for an exothermic reaction
- C. The conversion for a gas phase reaction increases with increase in pressure, if there is a
- D. decrease in volume accompanying the reaction
Explanation
For an exothermic reaction, heat behaves like a product, so increasing temperature shifts equilibrium backward and decreases the equilibrium constant. The pressure statements are consistent with Le Chatelier's principle when the volume change is specified.
