Midterm Question 1A

[Kessandra Ng 1K]

Hi! For question 1A about Q and Kp, why does Q have to be rounded to 1sf (in the midterm solutions it's 2 x 10^-2) even though it's just working out to the final answer?

I would think it is because the given Kp value, 3 x 10^4, has 1 sig fig along with the given temperature value, 700K. Hope this helps!

Thanks! I thought that Dr. Lavelle said didn't round anything until the end of the question/the final answer though? Especially since the question asked wasn't specifically telling us to find Qp.

Is it because you have to find Q in order to tell if the reaction is in equilibrium or not?
