The rate of reaction for N2+3H2→2NH3 is represented as

Hints to represent the rate of reaction(i) coefficients of reactants and products must be written as reciprocals(ii) Since concentration of reactants decreases with time negaive sign must be used to represent rate of reactantsNote: Rate of a reaction can never be negative(iii) Since concentration of products increases with time positive sign must be used to represent rate of products(iv) For the reaction, R → PFor the reaction, N2 + 3H2 → 2NH3
