When the concentration of a reactant is decreased which of the following is true?

Question

Quizplus · Accepted Answer

When the concentration of a reactant is decreased, the chance of successful collisions between reactant particles is reduced. This means that the frequency of collisions and the rate of reaction usually decrease, as there are fewer reactant particles available to react. However, there may be some cases where decreasing the concentration of a reactant actually increases the rate of reaction, such as when the reaction is limited by the presence of a catalyst. However, this is not always the case, so option C cannot be correct. Similarly, option A cannot be correct, as there may be some cases where the rate of reaction remains the same even when the concentration of a reactant is decreased. Therefore, the best choice is B, as it accurately reflects the common result of decreasing the concentration of a reactant.
