Question
![**Water Gas Production and Equilibrium Analysis**
**Overview:**
Water gas, a mixture of H₂ and CO, is an important industrial fuel produced by the reaction of steam with red hot coke, essentially pure carbon.
**Questions and Exercises:**
a. **Write the expression for the equilibrium constant for the reversible reaction:**
\[ \text{C (s) + H₂O (g) ⇌ CO (g) + H₂ (g)} \quad ΔH = 131.30 \text{ kJ} \]
b. **What will happen to the concentration of each reactant and product at equilibrium if more C is added?**
*Adding more C (solid) will not affect the equilibrium concentrations of the reactants and products in the gaseous phase because the concentration of a pure solid does not appear in the expression for the equilibrium constant.*
c. **What will happen to the concentration of each reactant and product at equilibrium if H₂O is removed?**
*Removing H₂O (g) will cause the equilibrium to shift to the left, favoring the formation of reactants to replace the removed H₂O (g).*
d. **What will happen to the concentration of each reactant and product at equilibrium if CO is added?**
*Adding CO (g) will shift the equilibrium to the left, favoring the formation of reactants to counteract the added CO (g).*
e. **What will happen to the concentration of each reactant and product at equilibrium if the temperature of the system is increased?**
*Since the reaction is endothermic (ΔH is positive), increasing the temperature will shift the equilibrium to the right, favoring the formation of products CO (g) and H₂ (g).*](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Ff90913a8-510d-485a-8226-8a0b61f2c858%2Fdefc4123-bccc-44ff-8528-fd849e2edcb9%2Fg1vup9d_processed.png&w=3840&q=75)
