aA + bB ⇌ cC + dD
Equilibrium expression linking the equilibrium concentration of reactants and products at equilibrium
CH3COOH (l) + C2H5OH (l) ⇌ CH3COOC2H5 (l) + H2O (l)
CaCO3 (s) ⇌ CaO (s) + CO2 (g)
For Kc expressions, it is important that you use square brackets as sometimes examiners are instructed to be strict about the appearance of brackets in expressions
Square brackets implies concentration
