![### Chemical Equilibrium and Reaction Rates
#### 4. Reaction Analysis
Both the forward and reverse reactions in the following equilibrium are believed to be elementary steps:
\[ \text{CO}(g) + \text{Cl}_2(g) \rightleftharpoons \text{COCl}_2(g) \]
**At 25°C,** the rate constants for the forward and reverse reactions are \(2.1 \times 10^2 \, \text{M}^{-1}\text{s}^{-1}\) and \(8.8 \times 10^9 \, \text{M}^{-1}\text{s}^{-1}\), respectively.
a. **Determine the equilibrium constant, \(K_c\), at 25°C for this reaction.**
b. **When equilibrium is reached, which is favored, products or reactants?**
#### 5. Reaction Equilibrium Analysis
**Consider the following reaction:**
\[ \text{H}_2(g) + \text{F}_2(g) \rightleftharpoons 2\text{HF}(g) \]
*At equilibrium in a particular experiment, the concentrations of \(\text{H}_2\), \(\text{F}_2\), and \(\text{HF}\) were \(0.11 \, \text{M}\), \(0.041 \, \text{M}\), and \(0.66 \, \text{M}\) respectively. What is the value of \(K_c\) for this reaction?*](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fe24fc82a-b7ed-4d5f-9001-130a2252ab39%2F6ac224ab-8661-42a3-b8e9-61322d3eafec%2Fynkxxq_processed.jpeg&w=3840&q=75)
