3. Consider the combustion of methane at 298 K, $$CH_4(g) + 2O_2(g) \rightarrow CO_2(g) + 2H_2O(g)$$ $$\Delta H = -890.4 kJ$$ Which one of the following best explains why this reaction is spontaneous at 298 K? A) $$\Delta S_{sys} > 0; \Delta S_{surr} < 0$$ B) $$\Delta S_{sys} < 0; \Delta S_{surr} < 0$$ C) $$\Delta S_{sys} \approx 0; \Delta S_{surr} > 0$$ D) $$\Delta S_{sys} > 0; \Delta S_{surr} \approx 0$$ E) $$\Delta S_{sys} \approx 0; \Delta S_{surr} \approx 0$$

Now use a new graph for each question below to show what happens to the equilibrium price and quantity for each of the following events. Make sure to include the initial supply (S1) and demand (D1) curves with their corresponding initial equilibrium price (P1) and Quantity (Q1) and then shift the Supply (S2) or Demand (D2) curve (not both) with the change in the Price (P2) and the Quantity (Q2). DRAW A NEW GRAPH FOR EACH QUESTION. The following questions/graphs should be in general terms, S1, S2, D1, D2, P1, P2, Q1, Q2. Thus the graphs do not need actual numbers, similar to the PowerPoint lectures. Email me if you any have questions. NOTE: This is what the midterm exam questions will be like and the graphs are worth 1/2 the points. 2) candy stops heart disease 3) the price of chocolate increases 4) Tech. advances in how candy is made 5) we tax candy.
