The correct Answer is:
To determine which of the given values does not represent the correct value of the universal gas constant (R), we need to analyze the units and values provided. ### Step-by-Step Solution: 1. **Understand the Universal Gas Constant (R)**: The universal gas constant (R) is a fundamental constant in chemistry that relates the energy scale to the temperature scale. It can be expressed in various units. 2. **List the Common Values of R**: - \( R = 8.314 \, \text{J K}^{-1} \text{mol}^{-1} \) - \( R = 0.0821 \, \text{L atm K}^{-1} \text{mol}^{-1} \) - \( R = 8.314 \, \text{Pa m}^3 \text{K}^{-1} \text{mol}^{-1} \) - \( R = 8.314 \times 10^2 \, \text{bar L K}^{-1} \text{mol}^{-1} \) 3. **Evaluate Each Option**: - **Option A**: \( 8.314 \, \text{Pa m}^3 \text{K}^{-1} \text{mol}^{-1} \) - This is a correct representation of R. - **Option B**: \( 8.314 \times 10^2 \, \text{bar L K}^{-1} \text{mol}^{-1} \) - This is also a correct representation of R. - **Option C**: \( 0.0821 \, \text{J K}^{-1} \text{mol}^{-1} \) - This value is incorrect because it does not match the standard value of R in Joules. - **Option D**: (Assuming another correct value) - This would be correct if it matches the known values of R. 4. **Identify the Incorrect Value**: After evaluating the options, it is clear that **Option C** \( 0.0821 \, \text{J K}^{-1} \text{mol}^{-1} \) does not represent the correct value of R. ### Conclusion: The value that does not represent the correct value of R is **C: 0.0821 J K^{-1} mol^{-1}**.
