WebExamples of state variables are temperature, pressure, volume, internal energy, enthalpy, and entropy. A state variable does not depend on the path by which the system arrived at its present state. For example, if I have 1 L of a gas, I can heat it, … WebExothermic and endergonic: Reaction of hydrogen and oxygen to yield water vapour, 2H2+O2 2H2O. This is an exothermic reaction (ΔRH<0) with decreasing number of particles (ΔRS<0). Only at temperatures at or below T with T⋅ΔS < ΔH an exothermic reaction may become endergonic.
