Thermodynamics

Question 1

Kinetic Energy

Answer 1

The energy that comes from movement. Temperature is the average of kinetic energy between particles

Question 2

Chemical Potential Energy

Answer 2

The energy that is stored in chemical bonds

Question 3

Enthalpy

Answer 3

The total amount of energy (sum of kinetic energy and chemical potential energy).

Question 4

Standard Enthalpy Change of Reaction

Answer 4

The change in heat energy transferred under standard conditions with reactants in their standard state

Question 5

Endothermic

Answer 5

A reaction in which the energy of the surroundings decreases. Products have higher energy than the reactants.

Question 6

Exothermic

Answer 6

A reaction in the energy of the surroundings increases. Products have lower energy than the reactants.

Question 7

Standard Enthalpy of Formation

Answer 7

The energy change when one mole of a compound is formed with everything in standard states

Question 8

Standard Enthalpy of Combustion

Answer 8

The energy change when one mole of a compound is combusted in oxygen in standard states.
