A-Level H2 Chemistry: Calculations Involving Partial Pressures/Pressures [Chemical Equilibria]
#seanchuachemistry #h2chemistry #alevelchemistry In this video, Mr Sean Chua, Chemistry Specialist of more than 20 years of teaching experience, demonstrates to his weekly JC 1 GCE A-Level H2 Chemistry Classes in Winners Education Centre, on the calculations involving concentrations in chemical equilibria. This video will explain the basic calculation in chemical equilibria using ICE table (Initial, Change and Equilibrium). But the ICE table is not always needed. When the equilibrium and starting concentrations of reactants and products are given, there is no need for ICE table. Note that for calculation of Kc/Kp, there is no need for ICE table as long as equilibrium concentrations (or partial pressures) are given. Master Basic Chemistry Concepts with Mr Chua!

#seanchuachemistry #h2chemistry #alevelchemistry In this video, Mr Sean Chua, Chemistry Specialist of more than 20 years of teaching experience, explains to his weekly JC 1 GCE A-Level H2 Chemistry Classes in Winners Education Centre, on the effects of catalysts on Kc or Kp. The main topic for this video is Chemical Equilibrium, which is an important topic that will be extended to other topics like Acid-Base Equilibrium and Organic Chemistry. Hence it is important to master this topic to apply to those more challenging topic. We use Le Chatelier's principle to explain the effect of changes on Kc or Kp. Catalysts only change the rate of reaction, not the extent. Hence, there will be no change in concentration of reactants and products in equilibrium. Thus, no change in Kc and Kp value.

#seanchuachemistry #h2chemistry #alevelchemistry In this video, Mr Sean Chua, Chemistry Specialist of more than 20 years of teaching experience, explains to his weekly JC 1 GCE A-Level H2 Chemistry Classes in Winners Education Centre, on the effects of changes in temperature on Kc or Kp. The main topic for this video is Chemical Equilibrium, which is an important topic that will be extended to other topics like Acid-Base Equilibrium and Organic Chemistry. Hence it is important to master this topic to apply to those more challenging topic. We use Le Chatelier's principle to explain the effect of changes on Kc or Kp. When there are changes in the temperature, it can either favor the endothermic or exothermic reaction, disrupting the equilibrium and the position of equilibrium shifts. Note that Kp is only used for reactions involving gases. Master Basic Chemistry Concepts with Mr Chua! Stay tuned for upcoming videos on Chemical Equilibrium!

#seanchuachemistry #h2chemistry #alevelchemistry In this video, Mr Sean Chua, Chemistry Specialist of more than 20 years of teaching experience, explains to his weekly JC 1 GCE A-Level H2 Chemistry Classes in Winners Education Centre, on the graphs of concentration against time, comparing the graphs for an irreversible and reversible reaction. The main topic for this video is Chemical Equilibrium, which is an important topic that will be extended to other topics like Acid-Base Equilibrium and Organic Chemistry. Hence it is important to master this topic to apply to those more challenging topic. Note that: Irreversible reaction means a complete reaction Reversible reaction means that the reaction does not go to completion. The main focus of chemical equilibrium is on reversible reaction.
