Partial pressures of A, B, C and D on the basis of gaseous system A+2B hArr C+3D are =0.20,B=0.10, C=0.30 and D=0.50 atm. The numerical value of equilibrium constant is

Answer»

`11.25`
`18.75`
5
`3.75`

Solution :`A+2BhArrC+3D`
`K=([pC][PD]^(3))/([PA][pB]^(2))=(0.30xx0.50xx0.50xx0.50)/(0.20xx0.10xx0.10)=18.75`
