Question
An endothermic reaction with high activation energy for the forward reaction is given by the diagram
Options
A.
B.
C.
D.
Solution
Reaction which involve absorption of heat energy are called endothermic reactions.Forsuch reaction
∑Hb > ∑HR
In graphs (c) and (d), the heat of product is more than heat of reactants and thus they represent endothermic reaction. But in (d) only small amout of energy is absorbed (less small difference between energy of reactants and products). Thus, (c) represents maximum activation energy.
