Question

For the reaction, 2N₂O_5(g) → 4NO_2(g) + O_2(g) in liquid bromine, which of the following rate
equation is INCORRECT?

a) `-1/2 (d[N_2O_5])/dt`

b) `-1/4 (d[NO_2])/dt`

c) `(d[O_2])/dt`

d) `1/4 (d[NO_2])/dt`

Answer 1

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

The instantaneous rate of the reaction is `-1/2 (d[N_2O_5])/(dt) = 1/4 (d[NO_2])/(dt) = (d[O_2])/"dt"`
