Answer: Increasing temperature.
- A Decreasing temperature
- B Increasing temperature
- C Increasing pressure
- D Adding catalyst
Correct answer: B. Increasing temperature
Explanation: For endothermic reactions, increasing temperature shifts equilibrium right and increases Kc.
As the reaction proceeds, reactant concentration falls and product concentration rises until both level off at equilibrium.
Concept context
When forward and reverse reaction rates are equal, equilibrium is reached. Learn about Kc, Kp, Le Chatelier's principle, and acid-base equilibria, including pH, buffer solutions, and solubility product.
