Question 1 · 1 mark · Difficulty 1/3

What is a reversible reaction?

  1. One where products can react to reform the reactants
  2. One that only goes one way
  3. One that produces a gas
  4. One that releases heat only
Show answer & explanation
✓ Answer: AOne where products can react to reform the reactants
In a reversible reaction the products of the forward reaction can react together to remake the original reactants.
