Question

Which statement best explains why reaction 1 requires a greater input of energy than reaction 2?
(1 point)
The bond energy of the reactants in reaction 1 is greater than the bond energy of the reactants in reaction
2.
The number of bonds in the reactants in reaction 1 is greater than the number of bonds in the reactants in
reaction 2.
The number of reactants in reaction 1 is greater than the number of reactants in reaction 2.
The bond energy of the products in reaction 1 is less than the bond energy of the products in reaction 2.

Answer 1

The statement that best explains why reaction 1 requires a greater input of energy than reaction 2 is:

**The bond energy of the reactants in reaction 1 is greater than the bond energy of the reactants in reaction 2.**

This is because a greater bond energy in the reactants means that more energy is required to break those bonds and initiate the reaction.
