You have 0.2 moles of a diatomic ideal gas in a volume of 0:005 m3 at atmospheric pressure and a temperature of 300 K. An electric heater now puts 6000 J of energy into the gas and the gas expands in volume, doing 3500 J of work on the outside world. The nal temperature of the gas is (in kelvins, closest answer)

i believe it is c.) 1575 j.

answer carbon and three oxygen atoms;

a). in this case, dh> 0 and sd> 0. if t becomes larger, the term "-tds" will become more negative. at some point, it is possible that -dts will be more negative than the dh is positive, and the reaction will become spontaneous. this is probably the correct answer, but you should look at all of the other possibilities and make sure of that.
