What is the amount of work done when 0.5 mole off methane, CH_(4)(g), – InterviewSolution

1.	What is the amount of work done when 0.5 mole off methane, CH_(4)(g), is subjected to combustion at 300 K? (Given, R=8.314JK^(-1)mol^(-1))
Answer» `-2494J` `-4988J` `+4988J` `+2494J` Solution :COMBUSTION of methane `CH_(4)+2O_(2)(G)toCO_(2)(g)+2H_(2)O(g)` `W=-pxxDeltaV=-nRT` `=-(-0.5)xx8.314xx300=+2494J`
