1.	The standard Gibbs energy change at 300 K for the reaction 2A hArr B +C is 2494.2J. At a given time, the composition of the reaction mixture is [A]=(1)/(2), [B]=2 and [C]=(1)/(2). The reaction proceeds in the : [R=8.314 J//K//"mol", e=2.718]
Answer» forward DIRECTION because `Q lt K_(e )` REVERSE direction because `Q lt K_(e )` forward direction because `Q GT K_(e )` reverse direction because `Q gt K_(e )` Solution :`DeltaG^(@)=2494.2J` `2A hArr B+C` `R=8.314 J//K"mol"`. e= 2.718 `[A]=(1)/(2), [B]=2, [C]=(1)/(2)` `Q=([B][C])/([A]^(2))=(2xx1//2)/((1)/(2))^(2)=4` `Delta G^(@)= - 2.303 " RT LOG " K_(e)` `2494.2J= - 2.303xx(8.314 J//K//"mol")xx(300K)log K_(e )` `implies " log " K_(e )= -(2494.2 J)/(2.303xx8.314 J//K//"mol" xx300K)` `implies log K_(e )= -0.4341` `K_(e )=0.37` `Q gt K_(e )`
