Question

$4H_3{PO}_3\underset{}{\overset{\Delta }{\to }}3H_3{PO}_4+{PH}_3$
The above reaction is disproportionation reaction. If true enter 1, else enter 0.

Answer 1

The reaction $4H_3{PO}_3\underset{}{\overset{\Delta }{\to }}3H_3{PO}_4+{PH}_3$ is a disproprotionation reaction as one molecule of $H_3{PO}_3$ is oxidized to $H_3{PO}_4$ and other molecule is reduced to $P{H}_3$.
