The rate for reaction, A+B ⟶ product, is 1.8 10^-2 mol dm^-3 s^-1. Calculate the rate constant if the reaction is second order in A and first order in B. ( [A ]=0.2M ; [B ]=0.1M )

Question

Accepted Answer

Correct answer: C. (c): For the given reaction, Rate =k [A ]^2 [B ] Given rate =1.8 10^-2 mol dm^-3 s^-1 [A ]=0.2M , [B ]=0.1M Rate constant (k )= Rate [A ]^2 [B ]= 1.8 10^-2 (0.2 )^2 (0.1 )=4.5 mol^-2 dm^6 s^-1

$The rate for reaction, A + B ⟶ product, is 1.8 \times 10^{- 2} mol dm^{- 3} s^{- 1} . Calculate the rate constant if the reaction is second order in A and first order in B . ([A] = 0.2 M; [B] = 0.1 M)$
