For a gaseous reaction, $\displaystyle \mathrm{A}_{(\mathrm{g})} \rightarrow 2 \mathrm{~B}_{(\mathrm{g})}+\mathrm{C}_{(\mathrm{g})}$, the rate of decomposition of $\displaystyle \mathrm{A}_{(\mathrm{g})}$ may be studied by measuring the pressure (P) in a system at constant volume (V) and temperature ( T ). If all the gaseous species follow ideal gas equation, then which of the relation is correct?
Official answer
(3)
Rate of reaction $\displaystyle =\frac{1}{2 \mathrm{RT}} \frac{\mathrm{dP}}{\mathrm{dT}}$
