State two units that the rate of a reaction can be measured in.
- 3Rates of Reaction
A tangent drawn to a volume-time graph at 15 seconds passes through the points (5 s, 6 cm3) and (25 s, 66 cm3). Calculate the rate of reaction at 15 seconds.
- 4Reversible Reactions and Equilibrium
The forward reaction of a particular reversible reaction is exothermic. State whether the reverse reaction is exothermic or endothermic.
