For each pair of quantities, explain which has a larger magnitude and why. Assume all gases are ideal gases.
a. CP(O2(g)) vs. Cv(O2(g))
b. CP(O2(g)) vs. CP(CH4(g))
c. qv vs. qp for the reaction: N2(g) + 3H2(g) -> 2NH3(g) ΔH = -92 kJ
d. w for the reaction 3N2H4(l) -> 4NH3(g) + N2(g) at constant pressure vs. w for the reaction 2H2O(l) -> 2H2(g) + O2(g) at constant pressure
e. ΔE vs. ΔH for the endothermic reaction: 2H2O(l) -> 2H2(g) + O2(g) occurring at constant pressure

1. Click the DeltaH is an Extensive Property button within the
activity, and analyze the relationship between the two reactions
that are displayed. The reaction that was on the screen when you
started and its derivative demonstrate that the change in enthalpy
for a reaction, ΔH, is an extensive property. Using this property,
calculate the change in enthalpy for Reaction 2. Reaction 1:
C3H8(g)+5O2(g)→3CO2(g)+4H2O(g), ΔH1=−2043 kJ Reaction 2:
3C3H8(g)+15O2(g)→9CO2(g)+12H2O(g), ΔH2=?

A gas phase reaction takes place in a syringe at a constant temperature and pressure. If the initial volume before reaction is 40 mL and the final volume after the reaction is complete is 70 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.) a. 2SO2(g) + O2(g)-->2SO3(g) b. 4PH3(g)-->P4(g) + 6H2(g) c. N2(g) + 3H2(g)-->2NH3(g) d....

The general form of a chemical reaction is aA + bB = cC +dD Where A and B are reactants in the forward direction and C and D are products in the forward direction. The lower case letters are the stoichiometric coefficients for the balanced equation. The general form of the equilibrium constant equation is then: Keq = [C]c[D]d/[A]a[B]b Part I: Q vs. K Q: reaction quotient can be calculated for a reaction at any concentration values of reactants and...
