HW question

Postby Kenan Kherallah 2C » Mon Feb 04, 2019 4:43 pm

Calculate the work that must be done against the atmosphere for the expansion of the gaseous products in the combustion of 1.00 mol C6H6(l) at 25 C and 1.00 bar.
(b) Using data in Appendix 2A, calculate the standard enthalpy of the reaction.

I just need the explanation as to why the answer in part a is positive and not negative. Thanks!

Work is being done by the system against the atmosphere, so work should be positive.
