![**Title: Understanding Pressure Calculations for CCl₄ Using Ideal and Van der Waals Equations**
**Objective:**
Calculate the pressure exerted by CCl₄ at 80°C with the following conditions: 1.00 mol occupying 33.3 L. Consider both ideal and van der Waals scenarios.
**Key Tasks:**
**1. Pressure Calculation Using the Ideal Gas Equation:**
- **Formula:** PV = nRT
- **Variables:**
- P = Pressure
- V = Volume (33.3 L)
- n = Number of moles (1.00 mol)
- R = Ideal gas constant
- T = Temperature in Kelvin (80°C)
**2. Pressure Calculation Using the Van der Waals Equation:**
- **Formula:** \((P + \frac{an^2}{V^2})(V - nb) = nRT\)
- **Variables:**
- a, b = Van der Waals constants specific to CCl₄
- Refer to Table 10.3 for values of a and b.
**3. Deviation from Ideal Behavior Analysis:**
- Consider which substance, Cl₂ or CCl₄, is expected to deviate more from ideal gas behavior under these conditions.
- Provide an explanation based on molecular interactions and size.
**Learning Outcomes:**
- Explore how real gases differ from ideal gases.
- Understand the applicability of the van der Waals equation for different gases.
- Evaluate deviations based on intermolecular forces and molecular size differences.
