Does the number of moles of reaction products increase, decrease, or remains same when each of the following equilibrium is subjected to a decrease in pressure by increasing the volume?
`PCl_(5)(g)hArrPCl_(3)(g)+Cl_(2)(g)`

Explanation

According to Le Chatelier's principle if the pressure is decreased on equilibrium the equilibrium shifts in the direction so that the increased pressure in nullified. Here the number of gaseous molecules (2) of products are more than the number of gaseous molecules (1) of the reactants the reaction proceed in the forward direction. So the number of moles of products increases.
