Answer:
The standard free energy change is -502.86 KJ
Explanation:
ΔG° = H° -TΔS°
where;
ΔG° is the standard free energy
H° is the standard enthalpy change = -631 kJ
ΔS° is the standard change in entropy = -430 J/K
T is the temperature of the system = 25⁰C = 298 K
Applying the formula above;
ΔG° = -631 kJ - ( -0.43J/K × 298K)
= -631 kJ + 128.14 KJ
= -502.86 KJ
Therefore, the standard free energy change is -502.86 KJ
Answer:
The particles move faster, and their average kinetic energy increases.
Explanation:
Molecules gain high kinetic energy which increases the velocity of them

Explanation:
Physical change is a change that does not affect the chemical composition of a substance but it changes the physical appearance like size or shape of the substance.
For example, crushing a can, melting of ice, breaking a glass etc represents the physical change.
Scenarios which represent examples of physical changes are as follows.
- Silicon is cut into tiny pieces for computer chips.
- Lead is melted to form pellets.
- Liquid water freezes to form ice.
