What is the effect of temperature on K(equilibrium constant)?

For this question we need to consider the equation:

ΔStotal = ΔSsystem - ΔH/T

For and exothermic reaction, -ΔH/T is po...

What is the relationship between K and ΔS total?

ΔStotal=RlnK

This equation means that if ΔStotal is large and positive then K is large (much greater than 1) and the position of equilibrium is well to the right (due to the equation ΔStotal =...

What is Le Chatelier's principle?

This is an quilibirum law tthat can be aplied to closed systems at dynamic equilibirum. Closed means that nothing can enter, nor leave the chemical system and dynamic equilibrium means that the rate o...

What is Le Chatelier's Principle?

The principle states that, if any system in dynamic equilibrium is subjected to a change, a process will act to minimise the change to restore equilibrium.
