Question

increasing the CH3Br concentration

reducing the OH concentration

cooling the reactant mixture

Please help with this question. I appreciate it. Thank you.
reducing the pressure of the reactant mixture

Answer 1

You can change the rate of the reaction by increasing OH or CH3Br (will increase rate) or decreasing OH or CH3Br (will decrease rate).
Cooling the reaction mixture will decrease the rate; increasing T will increase rate.
