Which of the following statements about the effect of temperature on reaction rates is true? high temperatures can change the ah between reactants and products the value of k in a rate law does not change at different temperatures high temperatures can decrease the activation energy of a reaction, increasing the reaction rate high temperatures increase the average kinetic energy of particles, increasing the reaction rate question 11 1 pts what are the units of k for the following rate law? rate k [a] [b] = m/s 1/s 1/(m2 s) 1/(m*s)
