Summarize the various factors that affect a system at equilibrium. Then briefly explain how pressure can affect the equilibrium Of some systems but not others.

(Can it be a short paragraph please)

The factors that affect the equllibrium are:

Explaination:

Effect of pressure:

There is no effect of pressure if the number of moles on the gaseous reactants and the number of moles on gaseous products are equalized.However it is different for total no of gaseous reactants and  total no of gaseous products.

If the total no of moles on the reactants are more than total no of moles of products,then low pressure will favor the forward reaction.

If the total no of moles on the products is more than total the no of moles of reactants,then high pressure will favor the forward reaction

explanation: no but i do not usually comment
