CHEM 1202 : Test 1 SOLUTIONS
Document Summary
The molar heat of combustion is (for 1 mole of propane) 0 grams of water are produced is q 45. There are three heats involved. (1) heat needed to raise the temperature to 100 c, (2) heat needed to vaporize the water, (3) heat needed to heat the gas to 100 c q 4. C 8 g 100 80 c. C 8 g 125 100 c. The formation reaction of carbon dioxide is elements in standard states 1 mole products. 2co (g) 2c (s) o2 (g) E q w is the only state function in the list. Path functions do not have to be the same for each path. Spontaneous means g and stot . To determine s look at the process (the reaction). We see that ions that occupy the entire liquid are created from a solid that is very localized in only one place. To determine ssurr look at the heat leaving or entering the surroundings.
