9.1- 9.3: Reversible Reactions

concentration of reactants

The ________ and products remains constant (given there is no other change to the system such as temperature and pressure)

Nitrogen

________ and hydrogen react together to form ammonia.

Equilibrium

________ means theres no overall change.

chemical equations

When writing ________ for reversible reactions, two arrows are used to indicate the forward and reverse reactions.

Le Chateliers Principle

________ states that when a change is made to the conditions of a system at equilibrium, the system automatically moves to oppose the change.

Nitrogen dioxide

________ can form dinitrogen tetroxide, a colourless gas.

Water of crystallisation

________ is indicated with a dot written in between the salt molecule and the surrounding water molecules.

II

When hydrated cobalt (________) chloride is heated, it loses its water of crystallisation and turns into anhydrous cobalt (________) chloride:

nitrogen

When only ________ and hydrogen are present at the beginning of the reaction, the rate of the forward reaction is at its highest, since the concentrations of hydrogen and ________ are at their highest.

II

When hydrated copper (________) sulfate is heated, it loses its water of crystallisation and turns into anhydrous copper (________) sulfate:

so the reaction can go i either direction

it is reversible

Example

 Iodine monochloride reacts reversibly with chlorine to form iodine trichloride
