When a mixture is stirred a) the rate of dissolving stops. b) the rate of dissolving will increase. c) the rate of dissolving will decrease. d) the rate of dissolving will remain constant.

Option (B) is the correct answer.

Explanation:

When we stir a mixture then it means we are increasing agitation into the solution which leads to increase in number of collisions between particles of the mixture.

As a result, rate of reaction will increase which will lead to increase in rate of dissolving.

Hence, we can conclude that when a mixture is stirred the rate of dissolving will increase.
