Question

Write the rate of reaction in terms of the rate of disappearance of reactant and the rate of formation of the product NO(g) +O3 _NO2(g) + O2(g)

Answer 1

See Explanation

Step-by-step explanation:

The rate of reaction means the same thing as the speed of a reaction. It refers to how quickly or slowly the reactants disappear or how quickly or slowly the products appear per unit time.

The equation of the reaction is; NO(g) + O3(g)→ NO2(g) + O2(g)

We can write differential equations to show the rate of disappearance of reactants or rate of appearance of products as shown below where the rate of reaction has been denoted as r;

r = -d[NO(g)]/dt = -d[O3(g)]/dt

OR

r = d[NO2(g)]/dt = d[O2(g)]

The negative signs shows that the concentration of reactants decreases with time while the positive sign shows that the concentration of products increases with time.
