Midterm Question 3B

Postby Abigail Sanders 1E » Wed Feb 19, 2020 3:18 pm

Can anyone explain the rationale behind the answer for midterm question 3B? On the test I used the rationale that the reaction with the fewest moles would produce the largest change in temperature for the same heat but this was marked incorrect? For reference the answer Dr. Lavelle posted is B.

The answer is B because it is the option where the acid and base have the highest molarity. A neutralization reaction with highly concentrated acids and bases will produce a lot of heat. If you think about baking soda and vinegar mixing, a large amount of heat is released in this reaction.
