Answer:did you get the answer
Explanation:
Answer:
b. milk spoiling and c. firecrackers exploding
Explanation:
These are both chemical changes, the composition of them change when this happens and it cannot be reversed
Answer:
When ΔS > ΔH/ T, then the reaction will proceed forward
Explanation:
- The entity that determines the whether a reaction will occur on its own in the forward direction (Spontaneity or Feasibility) is Gibb's free energy.
- Gibb's free energy is the energy available to do work. It is denoted as 'G'. It cannot be easily measured. The change (ΔG) can only be measured. ΔG = ΔH - TΔS
when ΔG is positive, The reaction is not spontaneous (reaction will not occur on its own)
When ΔG is negative, The reaction is spontaneous (reaction will occur on its own)
When ΔG is zero, the reaction is in equilibrium
Option A and E are not correct. ΔH (Enthalpy) cannot determine spontaneity
Option C and D cannot alone determine spontaneity of reaction
For reaction to be spontaneous, TΔS > ΔH
Therefore, ΔS > ΔH/T
