CHMS 2101 GENERAL CHEMISTRY Tutorial 2023

CHMS 2101: A one-page extract (questions 46-52) from a compiled General Chemistry multiple-choice revision set covering chemical equilibrium and physical chemistry. No course code, institution letterhead, or date appears on this page of the source, and the extract begins mid-sequence at question 46. Topics covered: converting Kc to Kp using the ideal-gas relation, identifying a heterogeneous equilibrium, defining an intensive property, applying the Clausius-Clapeyron equation to find vapor pressure at a different temperature, explaining surface tension as the cause of the water-skin phenomenon, identifying the intermolecular forces in HCl, and explaining why liquid viscosity decreases with rising temperature. A diagonal watermark and a promotional contact-information banner present on the source scan were not transcribed as they are not exam content.
