Which statement is INCORRECT with regard to kinetics? A. Each 10o C rise in temperature approximately doubles the rate of a reaction. B. The rate is expressed as the change in concentration per the change in time. C. The rate of reaction is always expressed as a positive value. D. The presence of a catalyst decreases the rate of reaction by lowering the Ea of the reaction. E. The effect that changing the concentration of a reactent has on the rate of a reaction must be determined experimentally.
