Question

Which of the following mixture does not obey Dalton's law of partial pressures?

• A. $S{O}_2+C{l}_2$
• B. $N{H}_3+P{H}_3$
• C. $C{O}_2+N_2$
• D. $CO+C{O}_2$

Answer 1

The correct option is A $S{O}_2+C{l}_2$

$S{O}_2+C{l}_2\to S{O}_{2}C{l}_2$
$S{O}_2+C{l}_2$ does not obey the Dalton's law of partial pressures because it is valid for non-reacting gases.
