Chapter 6: Q. 12 P (page 174)

Which reaction is faster, one with 螖骋#= +45 or one with 螖骋#= +70?

Short Answer

Expert verified

The reaction with 螖骋#= + 45is a faster reaction.

Step by step solution

01

Spontaneous reaction

Reactions that proceed without an external energy supply are called a spontaneous reaction.

For a reaction to be spontaneous, it needs to have a negative value of Gibbs free energy.

Also, for the reaction to be spontaneous, the value of螖厂掳 needs to be positive

02

Rate of reaction and ΔG# value

A fast reaction has a small螖骋# value. It means that smaller the value of螖骋# the rate of reaction is higher.

In the above case, there are two values for 螖骋#鈥攐ne is +45 and the second one is +70. Out of which +45 is thesmaller value so the reaction with 螖骋#= +45 is thefaster reaction.

2-Chloro-2-methylpropane reacts with water in three steps to yield 2-methyl-2-propanol. The first step is slower than the second, which in turn is much slower than the third. The reaction takes place slowly at room temperature, and the equilibrium constant is approximately 1.

  1. Give approximate values for螖骋卤 and 螖骋othat are consistent with the above information.
  2. Draw an energy diagram for the reaction, labeling all points of interest and making sure that the relative energy levels on the diagram are consistent with the information given.
