when to use ln
Hi! I was doing some of the textbook problems and I was confused about when I should use the equation on the equation sheet with ln of the concentrations and when to use the equations with just the concentrations and no natural log. Could someone explain when to use each equation?

Re: when to use ln
Hi!,
There are multiple equations that us natural log including:
ln [A] = -k t + ln 1/[A]o
ln k = - EA + ln A
Eo = RT/nF ln K
E = Eo - RT/nF ln Q
∆G=∆G°+RTlnQ
∆S = qREV ∆S = nR lnV2/v1
∆G°=-RTlnK
and more, via the equation sheet.
Is there a specific one you need help with?

Re: when to use ln
for a first order reaction, you would use the equation with ln when using the integrated rate, it really depends on what you're trying to find

Re: when to use ln
You would use the natural log when determining the half life of a first -order reaction, it is used when the integrated rate is involved. The natural log could also be used when determining the K value when the Activation energy and change in temperature are known.
