Chapter 20, Problem 1TC

To determine

The increasing order of reaction speed.

Answer to Problem 1TC

The increasing order for speed among the given reaction profiles are $\left(\text{c}\right)\text{<}\left(\text{a}\right)\text{<}\left(\text{b}\right)$ .

Explanation of Solution

The process of the conversion of reactant species into the product species is called a. chemical reaction. The term activation energy is used to describe the minimum amount of energy required for a reaction to complete. Thus the activation energy is the minimum required energy barrier which when passed by the reactant molecule can get converted into the product molecule to complete the reaction.

The reaction that has a lower barrier of activation energy proceed with a higher rate and the reaction that have a higher barrier of activation energy proceed with a lower rate.

Conclusion:

Therefore, the increasing order for reaction speed among the given reaction profiles are $\left(\text{c}\right)\text{<}\left(\text{a}\right)\text{<}\left(\text{b}\right)$ .
