For a chemical reaction A → B , it was found that concentration of B is increased by 0 . 2   mol…

For a chemical reaction AB, it was found that concentration of B is increased by 0.2 mol L-1 in 30 min. The average rate of the reaction is ________ ×10-1 mol L-1 h-1. (in nearest integer)

Solution

AB

t=0     0

t=30 min  0.2M

Av. rate of reaction =-Δ[A]Δt=Δ[B]Δt=(0.2-0)12

=0.4=4×10-1 mol/L×hr
