5. If you leave wine standing open to the air, oxygen will oxidize ethanol (the alcohol) to make acetic acid (which is vinegar):
C2H6O (aq) + O2 (g) -> HC2H3O2 (aq) + H2O (aq)
(ethanol) (acetic acid)
How many grams of acetic acid will you make if 5.00 grams of oxygen gas reacted?
6. Consider again the reaction that takes place when you burn propane gas:
C3H8 (g) + 5 O2 (g) -> 3 CO2 (g) + 4 H2O (g) + Δ
a) Is this reaction endothermic or exothermic?
□ endothermic □ exothermic □ need more information
b) What would happen to the rate of reaction if there were a decrease in the concentration of oxygen gas?
□ increase □ decrease □ no effect
c) What would happen to the rate of reaction if there were an increase in the concentration of propane gas?
□ increase □ decrease □ no effect
d) What would happen to the rate of reaction if the temperature of reaction were lowered?
□ increase □ decrease □ no effect
