The solution that will have the most successful collisions are:
B. A solution at high concentration and high temperature
Collision theory:
It is used to predict the rates of chemical reactions, particularly for gases. The collision theory is based on the assumption that for a reaction to occur it is necessary for the reacting species (atoms or molecules) to come together or collide with one another.
A decrease in temperature would have the opposite effect. With an increase in temperature, there is an increase in the number of collisions.
Thus, option B is correct.
