Here is a graph showing how the concentrations of the substances in a reaction vary over time (in a fixed volume): 1.0 [A] concentration /mol/L [B] time temperature increased from 10 °C to 20 °C A' is the reactant, 'B' is the product. Here is a puzzle: using only the information provided above, deduce as much as you an about this reaction. Start by writing the chemical equation for the reaction.

In the left-hand box, draw a particle diagram of the reactant molecules that produced the mixture shown on the right.

Classify each chemical reaction: Reaction 2Na(s) + Cl₂ (g) 2NaCl(s) 2Li(s) + 2HCl(aq) 2LiCl(aq) + H₂(g) H₂CO3(aq) → H₂O(l) + CO₂(g) K₂SO₂(aq) + Ba(NO³)₂(aq) → 2KNO3(aq) + -BaSO (s) Type choose one choose one choose one choose one X S >
