Parts and what they mean
- Actual total vapour pressure (वास्तविक कुल वाष्प दाब) — Lies BELOW the ideal line: A–B attractions are stronger than A–A and B–B, molecules escape less.
- Partial pressure of A (A का आंशिक दाब) — Also deviates from xA·pA⁰ in the same direction.
- Partial pressure of B (B का आंशिक दाब) — Also deviates from xB·pB⁰ in the same direction.
- Dashed lines: what Raoult’s law predicts (टूटी रेखाएँ: राउल्ट नियम की अपेक्षा) — An ideal solution would follow these straight lines exactly.
