Homework Answers
The rate of a reaction is decreased by decreasing the temperature because with decreasing the temperature the number of collision between reactant molecule decreases which lead into decrease in the rate of reaction
Pressure has no effect when we are using solid and liquid reactant And increasing concentration of reactant increase the rate of reaction .So these options are neglected
So 4th option is the correct option
