In a reaction, 2A Products, the concentration of A decreases from 0.5 mol L1 to 0.4 mol L1 in 10 minutes. Calculate the rate during this interval?


Given-


Initial concentration(A1) = 0.5M


Final concentration(A2) = 0.4M


Time = 10 mins.


The formula for average rate of the reaction is,


Equation 1


{A} = (A2)-( A1), the equation 1 is written as,




=


= 0.005 mol L-1 min-1


= 5 × 10-3 mol L-1 min-1


The average rate of the reaction is 5 × 10-3 mol L-1 min-1
