Standard enthorpyofX_(2), Y_(2) andXY_(3) are60,40 and50 JK^(-1) mol^(-1), respectively . For the reaction , (1)/(2)X_(2)+(3)/(2)Y_(2) to XY_(3), DeltaH= - 30 kJ to be at equilibrium, the temperature ofwill be

Answer»

1250 K
500 K
750K
1000K

Solution :`DeltaS = - 40 J//K`
`DeltaH =TDELTAS`
` T = 750 K`
