How does a positive catalyst generally affect a chemical reaction? A catalyst increases the temperature of the reaction which speeds the reaction rate. A catalyst reduces the frequency factor which speeds the reaction rate. A catalyst reduces the amount of solvent required which slows the reaction rate. A catalyst reduces activation energy which speeds the reaction rate.

The decomposition of hydrogen peroxide in dilute sodium hydroxide at 20 °C H2O2(aq)->H2O(1) + 12 02(g) is first order in H2O2- During one experiment it was found that when the initial concentration of 1,0, was 3.16x10-2 M, the concentration of H2O2 dropped to 8.09x10-3 M after 945 min had passed. Based on this experiment, the rate constant for the reaction is nin-1
