PH3 is highly poisonous it explodes with traces of oxidizing agent like HNO3-xA0-Cl2 and Br2 vapors-PH3-3Cl2-x2192-PCl3-3HCl-xA0-x394-H-x2212-veHence- PCl3 and HCl are formed and the mixture warms up as heat is evolved-

PH3 is highly poisonous it explodes with traces of oxidizing agent like HNO3, Cl2 and Br2 vapors.PH3+3Cl2→PCl3+3HCl; ΔH=−veHence, PCl3 and HCl are formed and the mixture warms up as heat is evolved.

$P H_{3}$ is highly poisonous it explodes with traces of oxidizing agent like $H N O_{3}, C l_{2}$ and $B r_{2}$ vapors.

$P H_{3} + 3 C l_{2} \to P C l_{3} + 3 H C l; Δ H = - v e$

Hence, $P C l_{3}$ and $H C l$ are formed and the mixture warms up as heat is evolved.
