How does the value of rate constant vary with reactant concentrations?

How does rate of reaction vary with activation energy ?

The reaction A+B to products is first order in each of the reactants. (a) How does the rate of reaction change if the concentration of A is increased by factor 3 ? (b) What is the change in the rate of reaction if the concentration of A is halved and concentration of B is doubled ?

How is rate constant related to concentration of the reactants?

Which of these factors affect the value of the rate constant for a reaction? (P) Temperature (Q) Reactant concentration (R) Use of catalyst
