Question:
Cox charts are plotted
Cox charts are plotted
Show Hint
Cox charts linearize the comparison of vapour pressures using logarithmic scales, simplifying correlation across substances.
Updated On: May 6, 2025
- Logarithm of vapour pressure of a substance versus logarithm of partial pressure of the reference substance
- Logarithm of vapour pressure of a substance versus logarithm of the vapour pressure of reference substance
- Logarithm of vapour pressure of a substance versus temperature
- Logarithm of vapour pressure of a substance versus partial pressure
Hide Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Step 1: Understand Cox chart use.
Cox charts are graphical tools used in chemical engineering to compare the vapor pressures of different substances.
Step 2: Cox chart plotting details. They plot: \[ \log(P) \text{ of the substance} \quad \text{vs.} \quad \log(P) \text{ of the reference substance} \]
