  1. Honors Chemistry Mr. Fredericks 2009-2010

  2. Tuesday, January 26th • Do Now: • Destroy Tokyo. Your tools are a paper clip, a rubber band, a pair of tube socks, and a ballpoint pen (no ink). • Objectives: • Learn about partial pressures, diffusion, and effusion. • Homework: • Quiz on Friday. • Read 14.4. Do problems #31, 34, 35

  3. Partial Pressure • Add ‘em up!Ptotal = P1 + P2 + P3 and so on • Typically used in kPa, but sometimes as percentages. • If you’re having trouble, you’re overthinking it.

  4. Random Motion of Gasses Diffusion Effusion Rate of escape Assume a tiny hole Low molar mass means high effusion • Rate of spread • Assume no physical barriers • Low molar mass means high diffusion
