(a) `PCl_(5)(g)hArr PCl_(3)(g)+Cl_(2)(g)`
(b) `N_(2)(g)+3H_(2)(g)hArr 2NH_(3)(g)`
(c ) `COCl_(2)(g)hArr CO(g)+Cl_(2)(g)`
(d) `CO(g)+2H_(2)(g) hArr CH_(3)OH(g)`

A

a, b

B

b, d

C

c, d

D

a, c

Text Solution

Verified by Experts

The correct Answer is:
D
`{:(A,+,B,rarr,2C),((3-0.75),,(1-0.75),,1.5):}`
`K=([C]^(2))/([A][B])=((1.5)^(2))/(2.25xx0.25)=(2.25)/(2.25xx0.25)=4.0`
