IB DP Chemistry: SL复习笔记7.1.2 The Equilibrium Law
The Equilibrium Constant Equilibrium expression & constant The equilibrium expression is an expression that links the equilibrium constant, Kc, to the concentrations of reactants and products a...
IB DP Chemistry: SL复习笔记7.1.1 The State of Equilibrium
The State of Equilibrium Reversible reaction Some reactions go to completion where the reactants are used up to form the products and the reaction stops when all of the reactants are used up In rev...
IB DP Chemistry: SL复习笔记6.1.8 Energy Profiles & Catalysis
Energy Profiles & Catalysis Catalysis is the process in which the rate of a chemical reaction is increased, by adding a substance called a catalyst A catalyst increases the rate of a reaction b...
IB DP Chemistry: SL复习笔记6.1.7 Maxwell-Boltzmann Curves
Maxwell-Boltzmann Curves Boltzmann distribution curve The Boltzmann distribution curve is a graph that shows the distribution of energies at a certain temperature In a sample of a substance, a few ...
IB DP Chemistry: SL复习笔记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复习笔记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复习笔记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复习笔记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复习笔记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...
