Which are true for the reaction: `A_(2) hArr 2C+D`?

Options

A. if `DeltaH=0, K_(p)` and increases with temperature and dissociation.
B. if `DeltaH=+ve, K_(p)` increases with temperature and dissociation of `A_(2)` increases.
C. if `DeltaH=-ve, K_(p)` decreases with temperature and dissociation of `A_(2)` increases.
D. `K_(p)=4alpha^(3)[P/(1+2alpha)]^(2)`

Answer

A, B, C, D

Explanation

`{:(,A_(2),hArr,2C,+,D),("Initial",1,,0,,0),("At equilibrium",1-alpha,,2alpha,,alpha):}`
`K_(p)=(2alpha)^(2)alphaxx[P/(Deltan)]^(2)=(4alpha^(3)P^(2))/((1+2alpha)^(2))`
Use `2.303 "log" (K_(2))/(K_(1))=(DeltaH)/(R)[(T_(2)-T_(1))/(T_(1)T_(2))]` for effect temperature on `K`
