How to rearrange to solve for an exponential function

Click For Summary
SUMMARY

The discussion focuses on rearranging the equation i=(io)exp(z*α*F*∆V)/(R*T) to isolate the variables io and α. To solve for io, the equation simplifies to io = i / (exp(z*α*F*∆V)/(R*T)). For α, the equation can be rewritten as (i / io)*R*T=exp(z*α*F*∆V), followed by applying the natural logarithm to yield z*α*F*∆V = ln((i / io)*R*T), allowing for α to be isolated. This process involves understanding exponential functions and logarithmic transformations.

I am having difficulty trying to rearrange this equation to solve for one unknown variable.

i=(io)exp(z*α*F*∆V)/(R*T)

How would I rearrange this equation if i wanted to solve for io, also how would I rearrange this equation to solve for say α.

Solving for i0 is trivial, your equation is basically
i = i0 * something
so
i0 = i / something.

To solve for α is a bit trickier, you can first rewrite it to
(i / i0)*R*T=exp(z*α*F*∆V),
then take the natural logarithm to get
z*α*F*∆V = ...
and finally solve that for α.
