# A reaction was found to be second order with respect to the concentration of carbon monoxide. If the concentration of carbon monoxide is doubled, with everything else kept the same, the rate of reaction will be Option 1) remain unchanged Option 2) tripled Option 3) increased by a factor of 4 Option 4) doubled

As we learnt in

nth order reaction -

The rates of the reaction is proportional to nth power of reactant

- wherein

Differential rate law
