$A$ reaction was found to be $2nd$ 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

$A$ reaction involving two different reactants:

The half-life of a reaction is found to be inversely proportional to the cube of its initial concentration. The order of the reaction is:

Considering the reaction $aG + bH \rightarrow \text{Products}$,when the concentrations of both reactants $G$ and $H$ are doubled,the rate increases by $8$ times. However,when the concentration of $G$ is doubled while the concentration of $H$ remains constant,the rate doubles. What is the overall order of the reaction?

Which of the following is a bimolecular reaction?

Which of these does not influence the rate of reaction?
