**Equilibrium Reaction Study**

**Reaction Details:**
Consider the chemical reaction:

\[ \text{CO}_{(g)} + \text{H}_2_{(g)} \leftrightarrow \text{C}_{(s)} + \text{H}_2\text{O}_{(g)} \]

with an equilibrium constant (\( K_c \)) of 17.9 at 125.0°C.

**Initial Conditions:**
Assume you start with a 500.0 mL flask containing:
- 0.5000 moles of carbon (\( \text{C}_{(s)} \))
- 1.500 moles of water vapor (\( \text{H}_2\text{O}_{(g)} \))
- 0.4630 moles of carbon monoxide (\( \text{CO}_{(g)} \))
- 0.2280 moles of hydrogen gas (\( \text{H}_2_{(g)} \))

**Tasks:**
a. Calculate the reaction quotient for this equilibrium process.

b. Determine the concentrations of all species at equilibrium.

c. Find the \( K_p \) for this reaction at 125.0°C.

**Answers:**
- Reaction quotient: 7
- Concentrations at equilibrium: 
  - Carbon monoxide: 3
  - Hydrogen gas: 0.7
  - Water vapor: 0.2
