Question

Which factor can decrease the rate of a chemical reaction?
1low activation energy
2high pressure
3 low temperature
4high concentration of reactants

Answer 1

According to me its low temperature that will decrease the rate of the chemical reaction.
As we increase the temperature,the kinetic energy of the molecule increases which will result in more number of collisions and will increase the rate of the chemical reaction.
Low temperature won't do the same work.
