Pressure-volume work
« on: October 07, 2013, 08:05:14 PM »
I'm looking for the pressure-volume work of a decomposition of 34.05 g. Given an P= 1.0236 ATM, P=103716.27 Pa, change in volume= 18.568. Would my final answer be w=-1925.8 KJ?

I think you know what it is.(Forum rules). Get the decomposition equation. All products are gases. Calculate the number of moles and use the equation:

W = nRTln(V1/V2)
