Question

A gaseous mixture was prepared by taking equal moles of $CO$ and $N_2$. If the total pressure of the mixture was found 1 atmosphere, the partial pressure of the nitrogen $\left(N_2\right)$ in the mixture is

• A. 0.5 atm
• B. 0.8 atm
• C. 0.9 atm
• D. 1 atm

Answer 1

The correct option is A 0.5 atm

$p_{CO}+p_{N_2}=1atm$
$2p_{N_2}=1$ $[\because n_{CO}=n_{N_2}]$
$p_{N_2}=\frac{1}{2}=0.5atm$
