![### Calculating Equilibrium Constants: Kc and Kp
**Problem Statement:**
Consider the equilibrium system described by the chemical reaction below. At equilibrium, a 5.0 L reaction vessel contained a mixture of 1.2 mol CH₄, 2.8 mol H₂S, 0.63 mol CS₂, and 0.042 mol H₂ at 93.0 °C. What are the values of Kc and Kp for the reaction at this temperature?
\[ \text{CH}_4(\text{g}) + 2 \text{H}_2\text{S}(\text{g}) \leftrightharpoons \text{CS}_2(\text{s}) + 4 \text{H}_2(\text{g}) \]
**To solve the problem, follow these steps:**
1. **Calculate the concentration of each species:**
- CH₄: \(\frac{1.2 \text{ mol}}{5.0 \text{ L}} = 0.24 \text{ M}\)
- H₂S: \(\frac{2.8 \text{ mol}}{5.0 \text{ L}} = 0.56 \text{ M}\)
- CS₂: \(\frac{0.63 \text{ mol}}{5.0 \text{ L}} = 0.126 \text{ M}\)
- H₂: \(\frac{0.042 \text{ mol}}{5.0 \text{ L}} = 0.0084 \text{ M}\)
2. **Set up the expression for \( K_c \):**
\[ K_c = \frac{[\text{H}_2]^4}{[\text{CH}_4][\text{H}_2\text{S}]^2} \]
3. **Insert the concentrations into the expression:**
\[ K_c = \frac{(0.0084)^4}{(0.24)(0.56)^2} \]
**Next Steps:**
The webpage includes an interactive component where users can select the correct values to place into the expression for \( K_c \). The options provided at the bottom include numerical values for the concentrations and other required multiplications.
