Questions & Step-by-Step Solutions

In a reversible reaction, if the forward reaction is exothermic, what can be said about the reverse reaction? (2022)
  • Step 1: Understand what a reversible reaction is. A reversible reaction can go in both directions: forward and backward.
  • Step 2: Identify what an exothermic reaction is. An exothermic reaction releases heat to the surroundings.
  • Step 3: Recognize that if the forward reaction is exothermic, it means heat is being released when the reactants turn into products.
  • Step 4: Know that the reverse reaction is the opposite of the forward reaction. It goes from products back to reactants.
  • Step 5: Conclude that if the forward reaction releases heat (exothermic), then the reverse reaction must absorb heat to proceed.
  • Step 6: Therefore, the reverse reaction is endothermic, meaning it requires heat from the surroundings.
