At room temperature, the equilibrium constant (Kw) for the self-ionization of water is 1.00 × 10−14. Using this information, calculate the standard free energy change for the aqueous reaction of hydrogen ion with hydroxide ionto produce water. (Hint: The reaction is the reverse of the self-ionization reaction.)
The standard free energy of formation, DGf°, of atomic oxygen is 230.1 kJ/mol. Determine the equilibrium constant for the following reaction at standard thermodynamic conditions.
O2(g) ↔ 2O(g)
Ammonia can be produced by the reaction of
hydrogen gas and nitrogen gas, as shown
below:
N2(g) + 3H2(g) → 2NH3(g)
Given that the standard free energy of formation
of NH3 (g) is -104 kJ/mol at 298 K, calculate the
equilibrium constant, K, at this temperature. To
express an answer in exponential notation, use E
to indicate the exponent. For example, 3.0 x 103
would be written, 3.0E3.
