Read the descriptions of physical or chemical changes in the table below. Then decide whether the change will be spontaneous, if you can. Change A solid absorbs heat and turns to a gas. During an endothermic chemical reaction, a gas is consumed and a liquid produced. During an exothermic chemical reaction, two moles of gaseous reactants are turned into four moles of gaseous products. OO O Is this change spontaneous? Yes. No. Can't decide with information given. Yes. No. Can't decide with information given. Yes. No. Can't decide with information given. X 5
which statement about entropy is true? non-spontaneous reactions sometimes will happen all by themselves entropy stops when pure substances are in solid state the entropy of the universe is increasing during a change of state there is no change in entropy

What happens to the entropy of an isolated system during an irreversible process?
1.) It is the study of the heat or energy involved in physical and chemical changes. Thermodynamics Thermochemistry Chemical Kinetics Chemical Equilibrium 2.) Which of the following refers to the first law of thermodynamics? The entropy of all thermodynamic systems and of all states of a system approaches a minimum value at absolute zero temperature (0 Kelvin). Two different thermodynamic systems that are in thermal equilibrium with a third thermodynamic system are said to be in thermal equilibrium with each other. Total entropy (S), the measure of randomness of energy, of any isolated thermodynamic system increases over time. Energy is conserved. 3.) It is the measure of the transfer of heat into and out of a system during a chemical reaction or a physical process Enthalpy Endothermic Reaction Calorimetry Exothermic Reaction
