# Partial Pressure Calculation

1. The problem statement, all variables and given/known data

I am given the following equation:

2NO (g) + Cl2 (g) $\rightleftharpoons$ 2NOCl (g)

Kp = 6.5×104
PNO = 0.35 atm
PCl2 = 0.10 atm

I need to calculate PNOCl.

2. Relevant equations

Kp = $\frac{(P_{NOCl})^2}{(P_{NO})^2*(P_{Cl_2})}$

3. The attempt at a solution

I was given Kp = 6.5×104

After plugging in my partial pressures for NO and Cl2 I got:

PNOCl = $\sqrt{(6.5×10^4)*(0.35)^2*(0.10)}$

Is this the correct way to calculate this?

Thanks!!
