In a reaction 2A product, the concentration of A decreases from 0.5 mol L-1 to 0.4 mol L-1 in 10 minutes. Calculate the rate during this interval.

Text Solution

Verified by Experts

Average Rate= `-1/2 (Delta[A])/(Delta t) =-1/2[([A]_3-[A]_1)/(Deltat_2-t_1)]= -1/2[(0.4 - 0.5)/10] =0.005 mol L^-1 mi n^(-1) = 5 times 10^-3 mol L^-1 mi n^(-1)`
