Question

Density of carbon monoxide is maximum at

• A. 0.5 atm and 273 K
• B. 4 atm and 500K
• C. 2 atm and 600 K
• D. 6 atm and 1092 K

Answer 1

Answer: (B)

From ideal gas equation,

$d=\frac{p M}{R T}$

$\because M$ and $R$ are constant for a particular gas

$\therefore d \propto \frac{p}{T}$, i.e.,

(a) $\frac{p}{T}=\frac{2}{600}=0.0033$

(b) $\frac{p}{T}=\frac{0.5}{273}=0.00183$

(c) $\frac{p}{T}=\frac{6}{1092}=0.00549$

(d) $\frac{p}{T}= \frac{4}{500}=0.0080$

$\because p / T$ ratio in highest at $4 atm$ and $500\, K$.

$\therefore $ Density of $CO _{2}$ is maximum at this condition.
