22. The concentrations of three gaseous chemicals are measured over time (see figure, below). Choose two different significant points in time for this reaction and explain what is happening at the chosen times. Support claims with evidence from course concepts. (3 marks) 2.50 200 1.50 1.00 - COCI, Cl₂ 0.50 0.00 10 20 Elapsed Time (s) 23. Propose one change for the chemical system at a time of 20 s (see figure, above) and predict what would happen to this system based on your proposed change. (1 mark) 24. The following reaction takes place: A,B 2A + B+ heat. If 3.00 moles of A,B are added into a 1.00 L container, it is found that 27.0 % of the reactant dissociates to reach equilibrium. Create an ICE table and solve for the K, of this reaction. Note: Show all calculations, follow the rules of significant figures, and box your final answer.
