Non-reversible reactions

Only proceed in one direction, reactants to products

Arrow symbol: non-reversible reactions

Single arrow →

Reversible reactions

Reactions that go in both forward and backward directions

Products in reversible reactions

React together to regenerate the reactants

Arrow symbol: reversible reactions

Reversible reaction example equation

H2+I2⇌2HIH_2 + I_2 ⇌ 2HI

CO2CO_2 leaving prevents what?

Backward reaction (gas escapes)

Forward: H2+I2H_2 + I_2 reaction

H2+I2→2HIH_2 + I_2 → 2HI

Backward: HIHI decomposition

2HI→H2+I22HI → H_2 + I_2

Example: non-reversible reactants

CH3COOHCH_3COOH + NaHCO3NaHCO_3
