Questions & Step-by-Step Solutions

What is the effect of increasing the temperature on the equilibrium constant Kc for an endothermic reaction? (2023)
  • Step 1: Understand what an endothermic reaction is. It is a reaction that absorbs heat from its surroundings.
  • Step 2: Know that the equilibrium constant Kc is a value that tells us the ratio of products to reactants at equilibrium.
  • Step 3: Recognize that increasing the temperature adds heat to the system.
  • Step 4: For an endothermic reaction, adding heat (increasing temperature) favors the formation of products.
  • Step 5: When the equilibrium shifts to the right (towards products), the concentration of products increases.
  • Step 6: As the concentration of products increases, the value of Kc also increases.
