When the concentration of alkyl halide is triple and concentration of `overset(Θ)OH` is reduced to half, the rate of `S_(N^(2))` reaction increased by :

When concentration of alkyl halide is tripled and the concentration of OH^(-) ion is reduced to half, the rate of S_(N)2 reaction increased by

When the concentration of nucleophile is reduced to half, the rate of S_(N^(2)) reaction is decreased by

When the concentration of nucleophile is reduced to half, the rate of S_(N^(2)) reaction is decreased by

S_(N)1 reaction of alkyl halides leads to :

Consider a reaction 2A +B to Products. When the concentration of B alone was doubled, the half life did not change. When concentration of A alone was doubled, the rate increased by two times. The unit of rate constant for the reaction is:
