According to kinetic molecular theory of gases,average kinetic energy of gas molecules is directly proportional to the absolute temperature.so increase of temperature increases the kinetic energy of gas molecules.Because of this velocity of gas molecules increases ,due to this number of activated collisions between the gas molecules also increases hence rate of reaction increases.Therefore increase of temperature increases the rate of reacton.your answer is correct.

I need help finding the rate law, the relationship between rate and k, and lastly how to find max k. Consider the following reaction which follows zero-order reaction kinetics 2 A(g) + Catalyst(s) → B(g) ΔH = -273.33 kJ Notice that the reaction is exothermic, so in a closed system it is possible for this to get out of hand: The reaction releases energy, which increases the temperature, which increases the rate, which makes it heat up faster, which...
