• A. $A$ $\rightarrow$ activation energy, $B$ $\rightarrow$ heat of reaction
• B. $A$ $\rightarrow$ threshold energy, $B$ $\rightarrow$ heat of reaction
• C. $A$ $\rightarrow$ heat of reaction, $B$ $\rightarrow$ activation energy
• D. $A$ $\rightarrow$ potential energy, $B$ $\rightarrow$ energy of reaction

Answer 1

Answer: (A)

Correct answer is (a) $A$ $\rightarrow$ activation energy, $B$ $\rightarrow$ heat of reaction
