Question

Question 20.56, chapter 20 of chemistry the central science.

I used standard reduction

potentials to calculate the equilibrium constant, at 298 K.

using the equation lnk = EnF/RT

I ended up with 35.8

is it better to find e^36 or e^35.8 ?

I’m guessing the non-rounded form is better, it gives me a k=3.5×10^15

e^36, gives k= 4.3 x 10^15

is it always better to calculate this using the non-rounded form? it seems to affect the equilibrium constant even by just a little.

Thank you!
