Decomposition of H2O2 follows a first order reaction . In fifty minutes the concentration of H2O2 decreases from 0.5 to 0.125 M in one such decomposition . When the concentration of H2O2 reaches from 0.05 M , the rate of formation of O2 will be A2 k1⇔k-1 2A For an elementary chemical reaction the expression for d[A]/dt is.
