Reversible reactions and equilibrium — practice question

The graph illustrates how the product yield in a reversible reaction varies when temperature and pressure are altered. Every reactant and product is a gas. $\text{reactants} \; \rightleftharpoons \; \text{products}$ Which row gives the correct answer for this reversible reaction?

  • Aside of reaction with fewer moles: reactant; forward reaction: exothermic
  • Bside of reaction with fewer moles: reactant; forward reaction: endothermic
  • Cside of reaction with fewer moles: product; forward reaction: endothermic
  • Dside of reaction with fewer moles: product; forward reaction: exothermic
