Heat of reaction for C(6)H(12)O(6(s))+6O...

Heat of reaction for `C_(6)H_(12)O_(6(s))+6O_(2(g)) rarr 6CO_(2(g))+6H_(2)O_(v)` at constant pressure is `-651 kcal` at `17^(@)C`. Calculate the heat of reaction at constant volume at `17^(@)C`.

Text Solution

AI Generated Solution

To calculate the heat of reaction at constant volume (ΔU) from the heat of reaction at constant pressure (ΔH), we can use the relationship derived from the first law of thermodynamics: \[ \Delta H = \Delta U + \Delta NRT \] Where: - \(\Delta H\) is the heat of reaction at constant pressure. ...
