Consider Cl2+F2=CLF3 (ΔH°f = -164.65 kJ/mol) . If 42 g of F2 is combined with 142 g of Cl2, how much grams of ClF3 can be produced? How much of the reagent is left over? What is the enthalpy change?
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 C is produced faster than D. 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 if one energy is less than another, that fact should be clear in your sketch. energy A + B Reaction 1 reaction coordinate energy A + B Reaction 2 reaction coordinate ☑
