Start with the concept explanation, then practise to create mastery evidence.
Learning objective
• K determined from stoichiometry • Deduce K expressions for homogeneous reactions
Start with the concept explanation, then practise to create mastery evidence.
Learning objective
• Magnitude indicates extent of reaction • Temperature dependent • Kreverse = 1/Kforward • Interpret K << 1, K < 1, K = 1, K > 1, and K >> 1
Start with the concept explanation, then practise to create mastery evidence.
Learning objective
• Predict effects of changes in concentration, temperature, pressure • Include effects on K and equilibrium composition
