Question

Why is the process of examining enthalpies of a reaction helpful? C or D?

A. It helps in determining how fast a reaction will proceed.
B. It helps in determining how a reaction occurs spontaneously.
C. It helps in determining which metal uses less energy during refining.
D. It helps in determining the temperature that a reaction requires to proceed.

Answer 1

I agree that A and B don't make sense.

Answer 2

And I don't think it is D because enthalpy doesn't tell us about reaction temp. It just tells us if it will release heat or absorb it.

Answer 3

It does tell us about energy consumption/release though. :)
