According to rate law: the rate of a reaction is proportional to the concentration of reactants raised to their powers of coeeficients.
Rate is proportional to [ concentration of reactant]0 (if the reaction is of zero order)
Rate is proportional to [ concentration of reactant]1 (if the reaction is first order.)
Rate is proportional to [ concentration of reactant]2 (if the reaction is second order)
So if the reaction is of first order, and the concentration of reactant is tripled then the rate is also triples.
If the reaction is of second order, and the concentration of reactant is tripled then the rate will become:
3^2 = 9 times.
if the reaction is of zero order, and the concentration of reactant is tripled then the rate remains the same..
