For the reaction,$2N_2O_5 \to 4NO_2 + O_2$,the rate of reaction is

Give the definition of the following terms:
$(i)$ Rate of Reaction
$(ii)$ Average rate of reaction
$(iii)$ Instantaneous rate

If the instantaneous rate of reaction is given as $-\frac{1}{a} \frac{d[A]}{dt} = -\frac{1}{b} \frac{d[B]}{dt} = \frac{1}{c} \frac{d[C]}{dt} = \frac{1}{d} \frac{d[D]}{dt}$,then the reaction is represented as:

For the reaction $5 Br_{(aq)}^{-} + BrO_{3_{(aq)}}^{-} + 6 H_{(aq)}^{+} \rightarrow 3 Br_{2_{(aq)}} + 3 H_{2}O_{(l)}$,write the rate of reaction expression.

What is the average rate of reaction when the change in concentration of product is $0.05 \ M$ in $20 \ s$ (in $M \ s^{-1}$)?

For a reaction $\frac{1}{2} A \rightarrow 2 B$,the rate of disappearance of $A$ is related to the rate of appearance of $B$ by the expression:
