For a reaction if `K_(p) gt K_(c)` , the forward reaction is favoured

1.	For a reaction if `K_(p) gt K_(c)` , the forward reaction is favoured by `(T gt 15K)`A. High temperatureB. Low temperatureC. Low pressureD. High temperature
Answer» Correct Answer - C `K_(p)=K_(c )(RT)^(Deltan_(g))` or `(K_(p))/(K_(c ))=(RT)^(Deltan_(g))` Now, `K_(p) gt K_(c) ( `given) `implies (K_(p))/(K_(c)) gt 1` `(RT)^(Deltan_(g)) gt1` At `T gt 15K` `RT gt 0.0821 xx 15 L ` atm `mol^(-1)` `RT gt 1.22 L` atm `mol^(-1)` `implies Delta n_(g) gt 0` `implies ` No. of moles of gaseous products `gt `No. of moles of gaseous reatants Such a reaction in the forward direction will favoured by low pressure.
