Identify the pair of gases that have equal rates of diffusion
- A \(\mathrm{CO}, \mathrm{NO}\)
- B \(\mathrm{N}_{2} \mathrm{O}, \mathrm{CO}\)
- C \(\mathrm{N}_{2} \mathrm{O}, \mathrm{CO}_{2}\)
- D \(\mathrm{CO}_{2}, \mathrm{NO}_{2}\)
Answer & Solution
Correct Answer
(C) \(\mathrm{N}_{2} \mathrm{O}, \mathrm{CO}_{2}\)
Step-by-step Solution
Detailed explanation
At constant pressure and temperature, the rate of diffusion or effusion of gas is inversely proportional to the square root of its density. Rate#0 of diffusion \(\propto \frac{1}{\sqrt{d}}\) \[ \frac{r_{1}}{r_{2}}=\sqrt{\frac{d_{2}}{d_{1}}}=\sqrt{\frac{M_{2}}{M_{1}}} \]…
