Gases : GasGramMixPressure (5 Variations)
4.80 g of CH4 is mixed with 17.6 g of CO2 in a 9.00 L flask at a temperature of 67.2oC. What is the total pressure of the flask? (Assume there is no reaction.)

Gases : GasMoleMixPressure (5 Variations)
What is the pressure exerted by a mixture of gases in a 40.0 L container at 127oC if the mixture contains 0.100 mol O2, 0.400 mol CH4, and 0.500 mol SO2?

Gases : GasRxnVolumes (10 Variations)
A gas phase reaction takes place in a syringe at a constant temperature and pressure. If the initial volume before reaction is 30 mL and the final volume after the reaction is complete is 15 mL, which of the following reactions took place? (Note: You can assume that you start with stoichiometric amounts of the reactants, the reaction goes to completion and that the gases behave ideally.)
Campbell's Rule for Estimating Entropy ChangesNorman C. Craig I am pleased that Campbells rule for estimating entropy changes in gas-consuming and gas-producing chemical reactions has attracted immediate interest. Craig, Norman C. J. Chem. Educ.2004, 81, 1571.

Campbell's Rule for Estimating Entropy ChangesWilliam B. Jensen In a recent article Norman Craig has proposed the rule-of-thumb that the approximate value of the entropy of reaction is related to the net moles of gas consumed or generated in the reaction .
