The value of K for the reaction at 25 °C is __________.

Chemical thermodynamics is the study of how heat and work relate to each other in chemical reactions and physical changes of state. It also involves a set of rules and laws that explain which processes can happen spontaneously and which need some help.  The primary goal of chemical thermodynamics is to determine the feasibility of a given transformation. It is used to predict energy exchanges in the following processes: Chemical reactions Phase changes Formation of solutions  The state functions that are most important in chemical thermodynamics are: Internal energy (U) Enthalpy...

Chemical thermodynamics is the study of how heat and work relate to each other in chemical reactions and physical changes of state. It also involves a set of rules and laws that explain which processes can happen spontaneously and which need some help. 

The primary goal of chemical thermodynamics is to determine the feasibility of a given transformation. It is used to predict energy exchanges in the following processes:
Chemical reactions
Phase changes
Formation of solutions 

The state functions that are most important in chemical thermodynamics are:
Internal energy (U)
Enthalpy (H)
Entropy (S)
Gibbs free energy (G)
