Consider that you have a balloon containing 2.00 moles of CO and 1.00 mole of O2 which is in a room that has a temperature of 28oC and a pressure of 1.00 atm. Then, the following reaction occurs inside the balloon to completion: 2 CO(g) + O2(g) -> 2 CO2(g). Calculate the change in work due to the reaction occurring inside the balloon. Enter your answer to three significant figures and in units of kJ.
Homework Answers
since at constant pressure and temperature work is done only whrn volume is changing .it is common that volume of a gas inside a ballon is decreasing with time .since workdone is positve .
Thank you.
