How many moles of O2 are required for the complete reaction of 1.60 moles of C2H4 to form CO2 and H2O? Use the balanced equation: C2H4 + 3O2 --> 2CO2 + 2H2O 113 mol
4.80 mol
48.0 mol
0.64 mol

Suppose a pair of chemical compounds a and b can react in two different ways: a + b -> c reaction 1 gives product c. a + b -> d reaction 2 gives product d. the following facts are known about the two reactions: . reaction 1 is endothermic and reaction 2 is exothermic. if a reaction vessel is charged (filled) with a and b , then at first d is produced faster than c. use these facts to sketch a qualitative reaction energy diagram for both reactions. note: because these sketches are only qualitative, the energies don? t have to be exact. they only have to have the right relationship to each other. for example, if one energy is less than another, that fact should be clear in your sketch.
