Kc & Kp
How do you know when to use Kc or Kp when dealing with gasses? For example, in problem 5I.17 we use Kc instead of Kp, why?

Re: Kc & Kp
It depends on the information we’re given. For 5I.17, the problem gives us Kc so we have to use that.

Re: Kc & Kp
I don't think it really matters when the question does not specify which to use. The calculations are the same.

I don't think you'll be marked down for using K.

I feel like they won't care on the test. But it can't hurt to take a look at the units and add the C or P.

Re: Kc & Kp
You can tell which one to use by what's given in the question; if the values are given in brackets, then you know the values are concentrations rather than partial pressures and you should use Kc.

Re: Kc & Kp
Kc is when the numbers given are concentrations while Kp is when the values are partial pressures.

Re: Kc & Kp
Are the calculations the same regardless of whether its concentration of partial pressure?
Re: Kc & Kp
We use kc when we are dealing with concentrations but we only use kp when we are dealing with partial pressures of gases.

Re: Kc & Kp
Is it possible for there to be an equation with both gaseous particles and aqueous solutions? How would we go about solving this? Would we use a combination of Kc and Kp?

i believe the calculations are the same so i think its okay as long as you account for any differences in units or something
