I believe it is three (3), temperature is the measure of the average Kinetic Energy, while heat is the measure of the transfer of thermal energy.
High temperature and pressure produce the highest rate of reaction. However, this must be balanced with the high cost of the energy needed to maintain these conditions. Catalysts increase the rate of reaction without affecting the yield. This can help create processes which work well even at lower temperatures.
I hope this helps you.
