Suppose we have this reaction, 2H3PO4⇒ P2O5 + 3H2Oand when the reaction rate is the speed at which the reagents can be changed and turned into products, So that, according to the equilibrium of the reaction:The rate of reaction = rate of formation of P2O5, and the speed of this reaction also = 0.5 rates of decomposition of H3PO4 ∴ the rate of decomposition of H3PO4 = 2 rate of formation of P2O5So when the rate of formation of P2O5 = 2 x 10^-4 M/s So that the rate of decomposition of H3PO4 = 2 x 2 x 10^-4 = 4 x 10^-4 M/s
