Represent Enthalpy 4 Ways (2 Min) - standard molar enthalpy, PE diagram 

There are 4 ways to represent enthalpy. It can be done through a thermochemistry equation by embedding the molar enthalpy within the equation, through an enthalpy value statement at the far right end of the balanced chemical equation, through a statement of a standard molar enthalpy or using an illustrative potential energy diagram (PE diagram). It is imperative to understand all four ways it can be interpreted since different questions or authors can present them in such various ways. It is a sort of language that needs to be understood to be fully comprehensive of various ways to tackle such problems.
