And how we relate it to equilibrium
Appreciated thanks

It basically relates to how many moles of products as opposed to reactants are produced..... and what type of products (their states) are produced. That is to say more moles, equal positive entropy and moreover having more moles of gaseous substances or liquids as opposed to solids, will also increase the overall entropy..
