IB DP Chemistry: SL復習筆記6.1.6 Explaining Rates
Explaining Rates Concentration The more?concentrated?a solution is, the?greater?the number of?particles?in a given volume of solvent An increase in?concentration?causes in an increased?collision fr...
IB DP Chemistry: SL復習筆記6.1.5 Rate Experiments
Rate Experiments During a reaction, the?reactants?are used up and changed into the?products This means that as the reaction proceeds, the concentration of the reactants is?decreasing?and the concen...
IB DP Chemistry: SL復習筆記6.1.4 Activation Energy
Activation Energy For a reaction to take place, the reactant particles need to overcome a minimum amount of energy This energy is called the?activation energy (Ea) In?exothermic reactions?the react...
IB DP Chemistry: SL復習筆記6.1.3 Measuring Rates
Measuring Rates To measure the?rate of a reaction, we need to be able to measure either how quickly the reactants are used up or how quickly the products are formed The method used for measuring de...
IB DP Chemistry: SL復習筆記6.1.2 Rate of Reaction
Rate of Reaction Reaction rate Some reactions take place instantly, but most are much slower and it is possible to measure how long these reactions take to reach a certain stage As a chemical react...
