Need help with simple Entropy mathematical question
« on: April 30, 2009, 10:18:54 PM »
Calculate the entropy change in the surroundings when 1 mol of N2O4(g) is formed from 2 mol of NO2(g) under standard conditions at 298K.

Which formula do we use? ???

Ah. It's alright. I figured it out using dS = dq/T but will need to find the enthalpy for the above reaction from experimental data values.
