What is the great evolutionary advancement of Angiosperms? Flowers and fruits. Flowers and fruits made co-evolutionary relationships possible with other species. (Gymnosperms have co-evolved with mycorrhizal fungi but we haven't discussed fungi - so we'll stick to Angiosperms.) What are the other species/groups that have co-evolved with Angiosperms and how have they influenced the evolution of flowers and fruits? How have flowers/fruits and those co-evolutionary relationships assisted in the adaptive radiation of Angiosperms and given them an evolutionary advantage over Gymnosperms?

The equilibrium constant, K, for the following reaction is 1.29×10-2 at 600 K. COCl2(g) CO(g) + Cl2(g) An equilibrium mixture of the three gases in a 1.00 L flask at 600 K contains 0.294 M COCl2, 6.16×10-2 M CO and 6.16×10-2 M Cl2. What will be the concentrations of the three gases once equilibrium has been reestablished, if 4.50×10-2 mol of CO(g) is added to the flask? [COCl2] = M
[CO] = M
[Cl2] = M

A 1:3 mixture of CO and H2 is passed through a catalyst to produce methane at 500 K. CO(g) + 3H2(g) = CH4(g) + H2O(g) How much heat is liberated in producing a mole of methane? How does this compare with the heat obtained from burning a mole of methane at this temperature? How does the heat of combustion of CH4 compare with the heat of compustion of CO+3H2? (Answers: 206.11 kJ is liberated; Burning CH4 liberates 802.34 kJ; Burning CO + 3H2 liberates 1008.45 kJ).

One method for producing hydrogen is to react coke (mostly solid carbon) with steam to make syngas, a mixture of CO and hydrogen
C(s) + H2O(g) ⇌ CO(g) + H2(g) Kp = 0.45 at 900 K ΔH = +131 kJ
What is the partial pressure of CO at equilibrium when 9.59 atm of H2O(g) is heated with excess C(s) at 900 K?
After equilibrium is reached, CO(g) is added.
In which direction will the reaction shift?
Will the equilibrium constant, K, increase or
decrease?
