Q

What’s Le Chateliers Principle?

A

If a stress (temp change or concentration change) is applied to a system at equilibrium the system readjusts to relieve the stress applied

Q

What were Le Chateliers finding?

A

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

Q

What is the meaning of a low equilibrium constant?

A

Less reactants were converted to products or less reactants were shifted to the right hand side of equation
