Question

For the formation of 3.65 g of hydrogen chloride gas, what volumes of hydrogen gas and chlorine gas are required at NTP conditions ?

• A. 1.12 L, 1.12 L
• B. 1.12 L, 2.24 L
• C. 3.65 L, 1.83 L
• D. 1 L, 1 L

Answer 1

Answer: (A)

1.12 L, 1.12 L

$H_2+C{l}_2\to 2HCl$

So 22.4 liters of $H_2,C{l}_2$ to produces $2\times 36.5$ grams that is 73 grams of $HCl$

So X liters of $H_2,C{l}_2$ produces $3.65$ grams of $HCl$.

$X=\frac{3.65\times 22.4}{73}=1.12$

Hence option $A$ is correct.
