Answer 1

Concept used: Le Chatelier's principle
Decreasing the volume will cause backward shift if change in gaseous moles is positive (i.e., $Δ n_{g} > 0$ ).
$K_{p} = K_{c} (R T)^{Δ n}$
So $K p < K c$ only if $Δ n_{g} < 0$ .
Increasing the pressure will favour backward reaction if $Δ n_{g} > 0$ .
Decrease of temperature favours forward reaction for exothermic reactions.

Answer 2

Concept used: Le Chatelier's principle
Decreasing the volume will cause backward shift if change in gaseous moles is positive (i.e.,

Δ n_{g} > 0

).

K_{p} = K_{c} (R T)^{Δ n}

So

K p < K c

only if

Δ n_{g} < 0

.
Increasing the pressure will favour backward reaction if

Δ n_{g} > 0

.
Decrease of temperature favours forward reaction for exothermic reactions.
