Question

Consider A+B---> products.

This reaction was experimentally determined to be second order in A and zero order in B.

Write down the rate law for this reaccion.

What would be the unit of rate constant 'k' for the above reation?
If the concentration of B is doubled (while keeping the concentration of A constant), by how much will the rate of the reaction change? What would be the unit of rate constant 'k' for the above reation?
If the concentration of B is doubled (while keeping the concentration of A constant), by how much will the rate of the reaction change?

Explanation / Answer

rate = K2[A]^2[B]^0


Units of nth order rate constant Kn = M^(1-n) time^-1

as it is a second order reaction

K2 = M^-1 time^-1


the rate of reaction can not change w.r.t. change in conc. of B

because order w.r.t B is zero that is why no chang in rate of reaction
