Solution

The correct option is A increases
The speed of a chemical reaction may be defined as the change in concentration of a substance divided by the time interval during which this change is observed.
Rate of reaction: If we increase the temperature the dissociation of reactants becomes more and the change in the concentration of reactants becomes more with respect to time.As rate of reaction is directly proportional to change in concentration of reactants or products rate of reaction increases with rise in temperature.
