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...
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...
A-level人文学科重要吗？ 重要！ A-level人文学科虽然没有常规科目选的人多，但在申请大学时很多专业是有指定要求的。 A-level心理学 大学心理学学位不要求必须学习过A-level Psychology。很多专业要求一门scienc...
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 ...
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...
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...
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 ...
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...
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...
