Question

Consider the reaction pathway graph below.

Which inference is supported by evidence in the graph?
The energy required to make the activated complex is greater than A + C.
This is an exothermic reaction where the total release of energy equals A + C.
The products need more energy to form than the reactants as shown by F.
This is an endothermic reaction because most of the energy is released at A.

Answer 1

First, define exothermic and endothermic.
