Which form of equation

[samanthaywu]

Which form of the Arrhenius equation is used more often / recommended for calculations: the one that solves for k or the one that solves for ln(k)?

[Charlie Russell 2L]

I think we are more likely to solve for k rather than ln(k). They are both similar.

Hi! personally I have found myself using the one that solves for k more frequently than lnk, but its pretty easy to go from one to the other.

They are both the same. I like to use the one that solves for k when I am looking for k but the one with ln(k) when I am looking for other variables.

I would recommend the one with k but you have to remember that the only difference is that one is taking the ln of both sides of the original equation. I think it really just depends on what you are trying to find since taking the ln of both sides is a step used to solve the equation usually.

I think ln k might be used a bit more because it is in linear form, which is easier to utilize and answer conceptual questions on. Both will give you the same answer to whatever the question may be, so feel free to use whichever one you feel more comfortable with.

Depends on what I'm solving for. If I'm solving for Ea or T, then I'd use the ln(k)=-Ea/RT + ln(A) because it doesn't need to be modified by a power/exponent or natural log. Rather if I'm solving for k or A, then k=Ae^(-Ea/RT) would be better imo.

I think it really depends on the problem and what it is asking you to solve, but I've found myself using the one that solves for k more often. But if I'm not solving for k and am solving for other variables instead, then I'd usually use the ln k one.
