Question

The ratio of gas constants of oxygen and hydrogen will be
1. 1 : 16
2. 1 : 8
3. 8 : 1
4. 16 : 1

Answer 1

Correct Answer - Option 1 : 1 : 16

Concept:

\({\left( R \right)_{any\;gas}} = \frac{{\bar R}}{{{{\left( {Molecular\;weight} \right)}_{gas}}}}\)

Calculation:

\(R{o_2} = \frac{{\bar R}}{{{{\left( {Mol.wt} \right)}_O}_2}} = \frac{{\bar R}}{{32}}\)

\({R_{{H_2}}} = \frac{{\bar R}}{{{{\left( {Mol.wt} \right)}_{{H_2}}}}} = \frac{{\bar R}}{2}\)

\({R_{{O_2}}}:{R_{{H_2}}}\)

\(\Rightarrow \frac{{\bar R}}{{32}}:\frac{{\bar R}}{2}\)

⇒ 1 : 16
