Question

Among the following mixture of gases, Dalton's law of partial pressures will not apply to which pair of gases?

• A. $H_2\text{and}S{O}_2$
• B. $H_2\text{and}C{l}_2$
• C. $H_2\text{and}C{O}_2$
• D. $C{O}_2\text{and}C{l}_2$

Answer 1

The correct option is B $H_2\text{and}C{l}_2$

Dalton's law is applicable only to a mixture of non-reacting gases. As $H_2\text{and}C{l}_2$ gases may react with each other to produce $HCl$ gas, Dalton's Law is not applicable.
