For the chemical reaction of ammonia combustion, write the expressions for velocity chemical reactions as a change in the concentration of all participants: 4 NH 3 (S ) + 5O 2 ( g )  4 NO ( g ) + 6 H 2 O ( g )

See explanation

Explanation:

We define the rate of reaction as the rate of disappearance of reactants or the rate of appearance of products. The negative sign written before the rate of change of concentration of reactants shows that their concentration decreases with time.

The rate of reaction in terms of the concentration of each reactant or product is shown below;

Rate = -1/4d[NH3]/dt

Rate = -1/5d[O2]/dt

Rate = 1/4d[NO]/dt

Rate = 1/6[H2O]/dt
