Answer: Rate of chemical reaction generally increases when temperature is raised.
Step-by-step explanation:
According to collision theory, more is the number of collisions between reactant molecules more will be the rate of reaction.
Therefore, when we increase temperature then molecules of reactant gain kinetic energy.
As a result, there will be increase in number of collisions hence, rate of reaction will increase.
Thus, we can conclude that rate of reaction increases when temperature is raised.
