Reaction Pathways — Quiz

Question 9 • 26-27 - C - RUSD Chemistry in the Earth System

Which statement best describes the reaction pathway graph for endothermic reactions?

Answer
A
always linear
B
mainly downhill
C
mainly uphill
D
always parabolic

Explanation

In an endothermic reaction, the products have higher energy than the reactants because the reaction absorbs energy overall. On a reaction pathway graph, this means the pathway ends at a higher energy level than it starts, so it is mainly uphill. The graph need not be perfectly linear or parabolic.
