The concentrations of products and reactants may change as a result of “equilibrium shifts” but the ratio of products to reactants as calculated using the equilibrium expression remains unchanged. Chapter 5. The name thermodynamics stems from the Greek words therme (heat) and dynamis (power). Topics are explained with practice problems throughout. Prinsip kekekalan energi : Energi tidak bisa diciptakan atau dimusnahkan tetapi hanya bisa dikonversi dari bentuk lain ke yang lainnya . heating of water in open air→ under atmospheric pressure) Isochoric → constant volume (e.
