Question

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
A. `11.25`
B. `18.75`
C. 5
D. `3.75`

Answer 1

Correct Answer - D
`A+2BhArrC+3D`
`K=([pC][pD]^(3))/([pA][pB]^(2))=(0.30xx0.50xx0.50xx0.50)/(0.20xx0.10xx0.10)=18.75`
