🤓 Based on our data, we think this question is relevant for Professor Cegelski & Schwartz Poehlmann's class at STANFORD.
We are being asked to calculate Kc for the given reaction:
2CH4(g) ⇌C2H2(g) + 3H2(g)
When dealing with equilibrium and Kc:
• Kc → equilibrium units in terms of concentration (i.e. molarity)
• Kc is an equilibrium expression:
▪ solid species are not included in the equilibrium expression
▪ the coefficient of each compound in the reaction equation will be the exponent of the concentrations in the equilibrium expression
Consider the following reaction: 2CH4(g) ⇌ C2H2(g) + 3H2(g)
The reaction of CH4 is carried out at some temperature with an initial concentration of [CH4] = 0.089 M. At equilibrium, the concentration of H2 is 0.016 M. Find the equilibrium constant at this temperature.
