Document Summary
What is the study of energy, heat, and work. What reaction is divided into systems and surrounding. What is abbreviated as s and us the measure if the randomness of a system. The change in internal energy of a system is equal to the product of work and heat. The universe tends toward increasing disorder or randomness. A substance that is perfectly crystalline at 0 k has an entropy of zero. What is the equation for free energy delta g= delta h- t delta s. What is the equation for the change in reactions. What are the variables for change in reactions. The number of calories of heat needed to raise the temp. What is the instrument used to measure specific heat. What is the study of rate or speed of a reaction. What factors affect reaction rates: size, temperature, concentration, nature of reactants, presence of a catalyst. What speeds up a reaction but is not permanently changed.
