For the reaction N2 +3H2 ---> 2 NH3, the rate of change of concentration for hydrogen is -0.3 x 10^-4 M/s. The rate of change of concentration of ammonia is?

The given equation isN2 + 3 H2  2 NH3-d [N2]dt = - 13d [H2]dt =  12d [NH3]dt- 13× 0.3 × 10-4 =  12d [NH3]dtd [NH3]dt = - 23× 0.3 × 10-4  = - 0.2 × 10-4 mol/sSince the formation of product should be represented with positive value, the rate of formation of ammonia is = 0.2 × 10-4 mol/s
