K is the equilibrium constant, the subscript In this equation ΔG° is the Gibbs Free Energy of a reaction under standard conditions of 1 atm (or 1 bar) for gases and 1 M for solutions at 25°C; ΔH° is the enthalpy of the reaction under standard conditions; T is the Kelvin temperature; and ΔS° is the entropy of the reaction under standard conditions.A spontaneous process has °G < 0.

Some focus more on notes, others on working through practice questions. The Chemistry formulas are always the preference of toppers of class. In your Chemistry II class, you need to master several formulas so you can calculate different mathematical problems ranging from kinetics, different types of equilibrium, thermochemistry, and electrochemistry.Chemists normally measure concentration in terms of molarity, M, and time is usually expressed in seconds, s, which means that the units of the reaction rate are M/s. chemistry help please Maths I got an A* (9) in GCSE Chemistry - AMA!
