How to Answer Equilibrium Graph Exam Questions // HSC Chemistry

This video discusses a step-by-step approach to answering equilibrium graph exam questions.

📚Syllabus
• Investigate the effects of temperature, concentration, volume and/or pressure on a system at equilibrium and explain how Le Chatelier’s principle can be used to predict such effects, for example:
– heating cobalt (II) chloride hydrate
– interaction between nitrogen dioxide and dinitrogen tetroxide
– iron(III) thiocyanate and varying concentration of ions (ACSCH095)

I just found the most golden channel ever! I seriously appreciate it and I wish great channel growth this year!

This was amazing! Understood this very well in time for my exam 😊 keep it up

isnt the forward reaction for t3 a decrease in temperature because an increase in temperature favours endothermic reaction but the forward reaction is exothermic

Your graph at t2 is incorrect. LCP predicts a partial change so when all concentrations increase, although there will be a shift to the right, the concentrations of all 3 will be higher than they were before. You have N2 and H2 being considerably lower than they were before. Guys if you are a VCE student watching this to help you, this graph would not score well on the exam. The other error in the graph is lack of showing the correct ratios. Yes you mention them verbally but they need to be shown explicitly in the graph. One mark out of 3 is for correct ratios. Fix these two issues and video would be great.
