Consider the following reaction:

Question

2NOCl(g) 2NO(g) + Cl2(g)
Initially pure NOCl(g) is placed in a vessel at 3.00 atm. At equilibrium, 0.416% of the NOCl has decomposed. Determine the
value for Kp.

Answer 1

........2NOCl ==> 2NO + Cl2
I.......3..........0.....0
C....-0.00416*3.0.0125...1/2*0.0125
E. ..etc.
