When S in the form of S_(g) is heated at 1000K, the initital pressure of 1 atm falls by 30% at equilibrium. This is because of conversion of some S_(g) to S_(2)(g) The K_(p) of the reaction is 0.011 "atm"^(-3)

Answer»

<P>`2.96 "atm"^(3)`
`1.71"atm"^(3)`
`204.8"atm"^(3)`
NONE of these

Solution :`S_(g)(g)hArr4S_(2)(g)`
`t-t_("eqm")1 "atm"-0.3"atm" 1.2"atm"`
`k_(p)=((1.2)^(4))/(0.7)=2.96 "atm"^(3)`
=0.7atm
