In catalytic reaction involving the formation of ammonia by haber's process N2+3H2-----??NH3 the rate of appearance of NH3 was measured as 2.5*10^ -4mole L^-1 S^-1 the rate of disappearance will be
rate of reaction=k[N2]^1 [H2]^3
rate of disappearance of NH3=2*rate of reaction
=2*(k[N2][H2]^3)
rate of disappearance of NH3=2*rate of reaction
=2*(k[N2][H2]^3)
