Explain the difference between instantaneous rate of a reaction and average rate of a reaction.

The rate of disappearance of $SO_2$ in the reaction $2SO_2 + O_2 \to 2SO_3$ is $1.28 \times 10^{-3} \ g/sec$. What is the rate of formation of $SO_3$?

For the reaction $N_2 + 3H_2 \rightarrow 2NH_3$ in the Haber process,the rate of formation of $NH_3$ is $2.5 \times 10^{-4} \ mol \ L^{-1} \ s^{-1}$. What is the rate of disappearance of $N_2$?

For the reaction $2N_2O_{5(g)} \to 4NO_{2(g)} + O_{2(g)}$,if the concentration of $NO_2$ increases by $5.2 \times 10^{-3} \ M$ in $100 \ s$,then the rate of reaction will be:

For the reaction $H_2 + I_2 \rightarrow 2HI$,state the correct differential rate law.

In a reaction $N_{2(g)} + 3H_{2(g)} \longrightarrow 2NH_{3(g)}$,the rate of appearance of $NH_3$ is $2.5 \times 10^{-4} \ mol \ L^{-1} s^{-1}$. The rate of reaction and rate of disappearance of $H_2$ will be (in $mol \ L^{-1} s^{-1}$):
