You are performing a titration experiment using a standard solution of 0.15M KOH and 15mL of an acid. You do not know the concentration or the identity of the acid, but it was neutralized by exactly 15mL of KOH. Using titration calculations, can you calculate the concentration of this acid? Explain why or why not.

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.
