Question

A chemical reaction can be reversed if?

The energy of the reactants exceeds the activation energy threshold.


The energy of the products exceeds the activation energy threshold.


The energy of the reactants is less than the activation energy threshold.


The energy of the products is less than the activation energy threshold.

Answer 1

Answer: The energy of the products exceeds the activation energy threshold.

Step-by-step explanation:

In the reverse reaction, the reactants of the forward reaction are now the products of the reverse reaction and vice versa.

This means that normally since you would need the energy of the reactants of the forward reaction to exceed the activation energy threshold, in the reverse reaction, the energy of the products would need to exceed the activation energy threshold.
