For the reaction 2SO_2(g) + O_2 (g) iff 2SO_3 (g) at 300K, the value of DeltaG^@ is - 690.9R. The equilibrium constant value for the reaction at that temperature is (R is gas constant)

Answer»

`10ATM^(-1)`
10atm
10

Solution :`2SO_2(g)+O_2(g) `/_\G=-RTlnk" or "=690.9R=-RTlnk`
or `(690.7)/(300)=INK " or "2.303=Ink" or "K=10`
`K_p=(p^2sO_3)/(p^2so_2xxpo_2)xx(atm^2)/(atm^3)=atm^(-1)`
