For reactions in solution, molar concentrations are usually used in equilibrium constant
expressions (designated by K or Kc). In gases, partial pressures can also be used (designated
by Kp). Equilibrium partial pressures of NOCl, NO and Cl2 in a container at 300 K are 1.2
atm, 0.050 atm and 0.30 atm, respectively. Calculate a value for the equilibrium constant Kp
for the following reaction.
2 2NO (g) + Cl (g) 2NOCl (g)
I found K =1920
my question is whether the temperature is being used at all and if it is why?
My calculator is broken so I can't check your calculation; however, no the temperature is not being used EXCEPT that the value for Kp calculated is at 300 K and no other temperature. Kp and Kc change with T.
