Question

A $5.0-L$ reaction vessel contains hydrogen at a partial pressure of $0.588atm$ and oxygen gas at a partial pressure of $0.302atm$. The limiting reactant in the following reaction:
$2H_2+O_2=2H_{2}O$ is:

• A. $H_2$
• B. $O_2$
• C. None of these
• D. Both (a) and (b)

Answer 1

The correct option is A $H_2$

$2H_2+O_2\leftrightharpoons 2H_{2}O$

$0.588$ $0.302$

Clearly limiting reagent is $H_2$.

Because required $H_2=2\times 0.302atm=0.604atm>$ Given amount
