is an exothermic reaction‚ meaning that heat is given off in the process. Because it gives off heat‚ the temperature cannot be controlled and this would affect my results‚ as there would be more than one dependent variable. I was only allowed H2O2 from the same source‚ which means no fresh source of H2O2 at a controlled temperature. I could not wait for the H2O2 to decompose to a certain temperature because that would take too long. I could not use the catalysts to help the H2O2 to decompose to that
