Question

The balanced equations for two reactions are shown.

(1) CH4 + N2 + H2 → CH3N + NH3

(2) CH4 + I2 → CH3I + HI

Which statement best explains why reaction 1 requires a greater input of energy than reaction 2?

  1. The number of reactants in reaction 1 is greater than the number of reactants in reaction 2.
  2. The number of bonds in the reactants in reaction 1 is greater than the number of bonds in the reactants in reaction 2.
  3. The bond energy of the products in reaction 1 is less than the bond energy of the products in reaction 2
  4. The bond energy of the reactants in reaction 1 is greater than the bond energy of the reactants in reaction 2.
