Question

4 moles of A are mixed with 4 moles of B. At equilibreium for the reaction `A+B hArr C+D.2` moles of C and D are formed. The equilibrium constant for the reaction will be
A. `1/4`
B. `1/2`
C. 1
D. 4

Answer 1

Correct Answer - C
`A+BhArrC+D`
`{:("Initial conc",4,4, 0,0),("After T time conc",(4-2),(4-2),0,0):}`
Equlibrium constant `=([C][D])/([A][B])=(2xx2)/(2xx2)=1`
