Equilibrium Constants
« on: March 08, 2013, 09:18:53 PM »
Consider the following reaction:
NH4HS (s)  ::equil:: NH3 (g) + H2S (g) at 25 °C

An equilibrium mixture of this reaction at a certain temperature was found to have [NH3]=0.278M and [H2S]=0.355M. What is the value of the equilibrium constants, Kc and Kp, for this reaction?

How do I find the equilibrium constants without knowing the equilibrium concentration of NH4HS?

Thank you!

One hint: What does the small s and g means behind the formulas? Does the coin falls down now? ;D

s stands for solid. g stands for gas.

Correct, but "cosmonautics" should answer this.  Wahat does this now mean to develop the eqilibrium cinstant?
