Chemical Equilibrium Flashcards
What is a reversible reaction?
Reaction which the products react to give back the reactants (reaction is going in both directions)
What is chemical equilibrium?
Is a state of dynamic balance where the rate of both the forward and backward reaction are the same
What’s a dynamic state?
Reacts are constantly forming products and products are constantly forming reactants
What’s a dynamic equilibrium?
Rate of forward reaction is equal to the rate of the backward reaction
What’s Le Chateliers Principle?
If a stress (temp change or concentration change) is applied to a system at equilibrium the system readjusts to relieve the stress applied
What were Le Chateliers finding?
In all gaseous reactions an increase in pressure with favour the reaction that brings about a reduction in volume, it’ll shift to the side with the smaller number of molecules
Name the Ideal conditions for maximum ammonia yield
High pressure (200atm) and low temp (500 degrees)
What’s ammonia used for?
Fertilisers explosives and cleaning agents
Write equation of ammonia manufacture
N2 + 3H2 -> 2NH3
iron catalyst may be used
Why is the ammonia factory located in Cobh?
Near to sea therefore easy export and easy access to methane (natural gas)
What is the meaning of a low equilibrium constant?
Less reactants were converted to products or less reactants were shifted to the right hand side of equation
