Question

Consider the following reaction at 25 °C:

Ba(OH)₂⋅8H₂​O(s)+2NH₄Cl(s)→BaCl₂​(s)+2NH₃​(g)+10H₂​O(l)

If ΔG∘=−14.1kJ/mol, determine the value of ΔG assuming that a mixture contains 12.0 g of Ba(OH)₂​⋅8H₂​O, 4.00 g of NH₄​Cl(s), 7.79 g of BaCl₂​, 1.83 atm of NH₃​, and 6.73 g of H₂​O.

Answer 1

The student is seeking to calculate ΔG for a reaction mixture containing specific amounts of substances. However, the question does not provide complete information to compute the reaction quotient Q, which is necessary to use with the formula ΔG = ΔG° + RTlnQ to determine ΔG for the non-standard conditions.

Step-by-step explanation:

The student is asking how to determine the value of ΔG for a given chemical reaction when the mixture contains specific amounts of reactants and products at 25 °C, given a standard ΔG° of −14.1 kJ/mol. The reaction is between Ba(OH)2·8H2O(s) and NH4Cl(s) to produce BaCl2(s), NH3(g), and H2O(l).

To solve this problem, we would need to compute the reaction quotient Q and use the formula ΔG = ΔG° + RTlnQ. However, since the question does not provide all of the necessary concentrations and partial pressures required to calculate Q, nor does it give enough information to determine the direction in which the reaction will proceed, a direct calculation cannot be performed based on the provided information.
