6th Edition, Question 1.55

Postby Tyra Nguyen 4H » Wed Oct 24, 2018 4:13 pm

Anybody know how to do question 1.55, part c? The wording of the question is slightly confusing to me, where it says "absorbing at 3500 cm-1".

It means to use the energy you got from part b of the exercise.
So, on the previous exercise, you would have for one absorbtion 7.2 * 10^-20J.
For the answer to part c, you would need to multiply that energy by Avogadro's constant.

Using the method given above ^ you should get 4.3 x 10^4 J/mol or 43 kJ/mol
