Question
A chemical reaction $2 A \longrightarrow 4 B+C ;$ in gaseous phase shows an increase in concentration of $B$ by $5 \times 10^{-3} M$ in 10 second. Calculate:(a) rate of appearance of $B$,(b) rate of the reaction,(c) rate of disappearance of $A$.
Step 1
In this case, the concentration of $B$ increases by $5 \times 10^{-3} M$ in 10 seconds. Therefore, the rate of appearance of $B$ is given by: \[ \frac{5 \times 10^{-3} M}{10 s} = 5 \times 10^{-4} M/s \] Show more…

2. A chemical reaction 2A ---- 4B + C in gas phase occurs in a closed vessel. The concentration of B is found to be by 5 x10 -3 mol L -1 in 10 seconds. Calculatea) The rate of appearance of Bb) The rate of disappearance of A
The rate of change in concentration of $C$ in the reaction; $2 A+B \longrightarrow 2 C+3 D$, was reported as $1.0 \mathrm{~mol}$ litre $^{-1} \mathrm{sec}^{-1} .$ Calculate the reaction rate as well as rate of change of concentration of $A, B$, and $D$.
The reaction; $2 \mathrm{~N}_{2} \mathrm{O}_{5} \longrightarrow 4 \mathrm{NO}_{2}+\mathrm{O}_{2}$, shows an increase in concentration of $\mathrm{NO}_{2}$ by $20 \times 10^{-3}$ mol litre $^{-1}$ in 5 second. Calculate (a) rate of appearance of $\mathrm{NO}_{2}$, (b) rate of reaction and (c) rate of disappearance of $\mathrm{N}_{2} \mathrm{O}_{5}$.
