QUESTION:

A chemist trying to synthesize a particular compound attempts two different synthesis reactions. The equilibrium constants for the two reactions are 23.3 and 2.2 * 104 at room temperature. However, upon carrying out both reactions for 15 minutes, the chemist finds that the reaction with the smaller equilibrium constant produces more of the desired product. Explain how this might be possible.

QUESTION:

A chemist trying to synthesize a particular compound attempts two different synthesis reactions. The equilibrium constants for the two reactions are 23.3 and 2.2 * 104 at room temperature. However, upon carrying out both reactions for 15 minutes, the chemist finds that the reaction with the smaller equilibrium constant produces more of the desired product. Explain how this might be possible.

ANSWER:

Solution:Step 1At room temperature.The given data is as follows.The equilibrium constant for first reaction. K. = 23.3 4The equilibrium constant for second reaction. K. = 2.2x 10The time period taken for the completing the both reactions for getting the required is 15minutes.
