I am struggling to with unseen organic chemistry mechanism. I don’t know where to begin drawing them.

The purpose of a mechanism in organic chemistry is to show the movement of electron density leading to the reaction. Keeping this in mind, when faced with the starting materials, the first thing to identify ...

How does a catalyst and increasing temperature affect the rate of reaction?

For a reaction to occur between particles (reactants) they must overcome an energy barrier. This is called the activation energy. A catalyst provides an alternative pathway for the reaction, that has a lower...

Explain Le Chatelier's Principle and the factors that affect the position of equilibrium

Le Chatelier's principle states that is there is a change in concentration, pressure or temperature, the equilibrium will move in order to counteract the change. Firstly temerature - in an reversible reactio...
