The reaction of phosphine gas with chlorine gas is given as,

$\mathrm{P}{\mathrm{H}}_3+4\mathrm{C}{\mathrm{l}}_2\to \mathrm{P}\mathrm{C}{\mathrm{l}}_5+3\mathrm{H}\mathrm{C}\mathrm{l}$

Therefore, the products formed when phosphine gas is mixed with chlorine gas are${\text{PCl}}_{\text{5}}$and$\text{HCl}$.

The mixture will cool down later.
