CHEMICAL EQUILIBRIUM Flashcards
The amount in mole of the products at equilibrium are equal
True/false
True
What are the products electrolysis of brine (aqueous Nacl)
Chlorine at the anode
Hydrogen at the cathode
NaOH
What are the uses of chlorine
It’s used for disinfectants, pesticides, anesthetics, plastics, CFCs, bleaching
What are the uses of NaOH
It’s used for making synthetic fibres, detergents, soap
What is electroplating, and what is the arrangement of the cell
Electroplating is the process of coating a metal with another metal through electrolysis.
The anode is the coating substance, the cathode is the material to be coated, the electrolyte is the salt of the coating material
What is electrorefining
It is the process of electrolysis where pure metals are deposited at the cathode
What are the materials deposited at the anode during electrorefining called
Anode mud
State the law of mass action
The law of mass action states that the driving force of a reaction is proportional to the active masses of the reacting substances
What is the equilibrium constant
Keq = [C]^c[D]^d/[A]^a[B]^b
What is the relationship between Kp and Kc
Kp = Kc(RT)^n
n= (c+d) - (a+b)
(XCP)^c . (XDP)^d/(XAP)^a . (XBP)^b
Is the formula for calculating
Kp
What is Homogenous equilibria and the types
It is a reaction in which the products and reactant are in the same physical state
Gaseous equilibria
Liquid equilibria
State Le Chatelier’s principle
It states that if there is a chemical system at equilibrium where one of the factors that affect equilibrium(concentration, pressure, temperature) is altered, the equilibrium will shift so as to annul the effect of the change
What is a solution
A solution is a mixture of two or more substances with varying proportions
Classification of solutions are based on what
Relative amount of solute to solvent
Solute size
Interaction between solute and solvent
