Question
Chapter 2, Problem 63P
Interpretation Introduction
Interpretation:The type of reaction represented by the below energy profile diagram should be chosen.
Concept introduction:The reactions that are accompanied by absorption of energy by substrates so as to form product are termed as endothermic reaction.The reaction profiles for such reaction are illustrated below.
The reaction that liberates energy when reactants are converted to products is termed as exothermic reaction. The reaction profiles for such reaction are illustrated below.
