IB DP Chemistry: SL复习笔记8.1.3 Characteristic Reactions of Acids
Characteristic Reactions of Acids Metals and acids The typical reaction of a metal and an acid can be summarized as acid + metal → salt + hydrogen For example: 2HCl (aq) + Zn (s) → ...
IB DP Chemistry: SL复习笔记8.1.2 Conjugate Acid-Base Pairs
Conjugate Acid-Base Pairs A Brønsted-Lowry acid is a species that can donate a proton A Brønsted-Lowry base is a species that can accept a proton In a reaction equilibrium the products are formed a...
IB DP Chemistry: SL复习笔记8.1.1 Brønsted–Lowry Acids & Bases
Brønsted–Lowry Acids & Bases The Brønsted-Lowry Theory defines acids and bases in terms of proton transfer between chemical compounds A Brønsted-Lowry acid is a species that gives away a proton...
IB DP Chemistry: SL复习笔记7.1.6 Catalysts & Equilibrium
Catalysts & Equilibrium Changes in concentration If all other conditions stay the same, the equilibrium constant Kc is not affected by any changes in concentration of the reactants or products ...
IB DP Chemistry: SL复习笔记7.1.5 Le Chatelier's Principle
Le Chatelier's Principle Position of the equilibrium The position of the equilibrium refers to the relative amounts of products and reactants in an equilibrium mixture. When the position of equilib...
IB DP Chemistry: SL复习笔记7.1.4 The Reaction Quotient
The Reaction Quotient The reaction quotient, Q, is the ratio of products and reactants for a reaction that has NOT yet reached equilibrium The expression for Q is very similar to Kc: It is a useful...
IB DP Chemistry: SL复习笔记7.1.3 Equilibrium Constant Relationships
Equilibrium Constant Relationships In the previous section we saw that the concentrations of the substances are raised to the power of the coefficients from the balanced equation This means the Kc ...
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...
