a. For which of the following reactions, `K_(p)` is equal to `K_(c)` ?
i. `H_(2)+I_(2)hArr2HI`
ii. `N_(2)+3H_(2)hArr2NH_(3)`
iii. `PCl_(5)hArrPCl_(3)+Cl_(2)`
b. For which of the following cases does the reaction go garthest to completion:
`K=1, K=10^(10), K=10^(-10)`?

Text Solution

Verified by Experts

For reaction `H_2+I_2 Leftrightarrow 2HI` only
i.e, Eqn. (3) reduces to `K_p=K_c.`
(b) The reaction having `K=10^(10)` will go farthest to completion because the ratio [product]/[reactant] is maximum in this case [Eqn. (1)].
