when mixing 10ml 0.5 M HNO3 and
20ml
0.08 m Ca(OH)2
b) 0.18kJ
a) 0.12 kJ
0.24 kJ
d) 0.09 kJ​

Answer 1

Answer:

To know the relationship between free energy and the equilibrium constant.

The sign of the standard free energy change ΔG° of a chemical reaction determines whether the reaction will tend to proceed in the forward or reverse direction.

Similarly, the relative signs of ΔG° and ΔS° determine whether the spontaniety of a chemical reaction will be affected by the temperature, and if so, in what way.
