#### Question

For the reaction

2N_{2}O_{5} (g) → 4NO_{2} (g) + O_{2} (g), the rate of formation of NO_{2} (g) is 2·8 × 10^{–3} M s^{–1}. Calculate the rate of disappearance of N_{2}O_{5} (g).

#### Solution

A rate of formation of NO_{2} = 2·8 × 10^{–3} M s^{–1}

A rate of Disappearance of N_{2}O_{5} =

`- 1/2 (d[N_2O_5])/(dt) = 1/4 (d[NO_2])/(dt)`

`(d[N_2O_5])/(dt) = 1/4 xx 2.8 xx 10^(-3) xx 2 = 1.4 xx 10^(-3)`

`= 1.4 xx 10^(-3) Ms^(-1)`

Is there an error in this question or solution?
