PL20.1. Free Energy
Consider the reaction below:
A(aq) B(ag) AG
ㄹ
= 2.79 kJ
rxn
A 1.000 M solution of A was heated at 62.0 C for several hours. After some time the
concentration of A was determined. Answer the following questions:
a) What is the maximum amount of work (AG) from/for this reaction when
[A] = 0.922 M?
AG (kJ)
b) What is the concentration of B when AG = -3.54 kJ?
[B] M =
= number (rtol=0.03, atol=1e-08)
=
number (rtol=0.03, atol=1e-08)
c) Determine when AG = -5.08 kJ?
number (rtol=0.03, atol=1e-08)
