Melting and vaporization are examples of exothermic process.

Reactions in which the products can react to form back the reactants are said to be ___.

What happens to the internal energy of the system if work is done on the system?

Determine the change in the standard entropy, ΔS⁰, for the synthesis of carbon dioxide from graphite and oxygen:

       C(s) + O2(g) → CO2(g)

Standard Entropy in J/mol.K  for:      C= 5.740                    O2 = 205.14   CO2=213.74    

Calculate the number of kJ necessary to raise the temperature of 80 grams of aluminum from 45 to 65 degrees Celsius. Molar heat capacity of aluminum is 24 J/mole.K. 

Chemical equilibrium is described as a dynamic process because there is a movement in which the forward and reverse reactions occur at the same rate to reach a point where the amounts or concentrations of the reactants and products are unchanging with time.

____ constant tells how far the reaction has proceeded once the equilibrium is reached.

In thermodynamics, an ___process, also called a constant-volume process.

A reversible reaction has ΔG negative for forward reaction. What will be the sign for the backward reaction?

What happens to the internal energy of the system if work is done by the system?
