Conditions for Standard Enthalpy

Postby Yoon Lee 2A » Sat Jan 09, 2016 7:48 pm

The standard conditions are 25 deg Celsius and 1 atm...how come there is no standard for volume? Is it because volume depends on the numbers of moles of a gas there are?

If I understand your question correctly, the "condition" for volume in terms of enthalpy of a reaction is simply that the reaction must occur at a constant volume. As a result, we can say that the enthalpy of a reaction is the same as the change in internal energy.
