### Kp

Can we use values with both atm and bar in Kp for gases (not in the same calculation, but separately)? For example, if the problem gives gas pressure values in atm, we wouldn't need to convert to bar?

As long as you keep the units consistent throughout a single problem, you can use both bars and atm to calculate Kp, depending on which one is given in a problem.

You can convert between atm and bars when dealing with partial pressures depending on the question/problem. 1atm is approximately equivalent to 1.01325 bars

I think any unit is fine as long as it's consistent throughout the equation.

### Re: Kp

you wouldn't need to convert, but make sure to keep all the units the same because Kp is a ratio.

I'd say use either one it's fine, just make sure all are the units are the same in a problem just to avoid any calculation mistakes.

You can use either units for the Kp value, but you have to keep it consistent throughout your equation.

As long as the units are consistent within the problem, any units of atm or bars is alright.
