U3 Equilibrium
A system in which a reversible chemical reaction can reach a state of dynamic equilibrium where matter cannot be exchanged but energy can.
What is a closed system?
The group of organic compounds that act as Bronsted-Lowry acids by donating protons in solution.
What are carboxylic acids?
An electrochemical device that converts chemical energy into electrical energy through a spontaneous oxidation-reduction reaction.
What is a galvanic cell?
A functional group comprised of an oxygen and a hydrogen.
What is a hydroxyl group.
This is Mrs Ganes favourite colour.
What is green.
For the equation N₂(g) + 3H₂(g) ⇌ 2NH₃(g), this is the direction of equilibrium shift when the volume of the reaction container is decreased at constant temperature.
What is a shift to the right?
A chemical substance that only partially accepts protons (H+) or dissociates in an aqueous solution, establishing a dynamic chemical equilibrium rather than going to completion.
What is a weak base?
The outcome of the standard potential at the cathode minus the standard potential at the anode.
What is an E0 cell value?
The classification given to a compound made of carbons and hydrogens that includes a double bond or multiple along the carbon chain.
What is an unsaturated hydrocarbon.
This is where Mr Gane was born.
What is Mareeba FNQ
The reaction pathway taken by a chemical system when heat is increased but the volume of the reaction chamber is constant.
What is an endothermic pathway?
The name given to an acid that can donate more than one proton per molecule, common examples are sulfuric acid and phosphoric acid.
What is a polyprotic acid?
25°C (298 K), 100 kPa and 1 M.
What are standard conditions?
What is 2,4-dimethylpent-2-ene
This is the name of a sport that Mr Gane was at a representative level in during his high school years and in his 20's.
What is Rugby Union.
This is the value of Kc at a particular temperature, where the reaction is 2SO₂(g) + O₂(g) ⇌ 2SO₃(g) and [SO₂] = 0.20 mol L⁻¹, [O₂] = 0.10 mol L⁻¹ and [SO₃] = 0.40 mol L⁻¹.
What is Kc = 40?
A solution containing equal amounts of a weak acid and its conjugate base, or a weak base and its conjugate acid, which can resist change in pH when small amounts of acid or base are added.
What is a buffer?
The standard potential value of a galvanic cell comprising of magnesium and iodine gas.
What is 2.5V?
What is ethyl butanoate
What is Singapore
The concentration of lead (II) ions in a solution of lead (II) bromide where the solubility product at 25°C is 6.6 × 10–6.
What is 0.0118M?
This number is equivalent to Ka of a weak acid in a solution multiplied by the Kb of its conjugate base.

Produced at the anode of an electrolytic cell where the electrolyte is 2M magnesium chloride.
What is chlorine gas.
An asymmetric carbon that is bonded to four completely distinct groups or atoms.
What is a chiral carbon.
