To solve the problem, we will use the relationship between Gibbs free energy (ΔG), enthalpy (ΔH), and entropy (ΔS) at a given temperature (T). The equation we will use is: \[ \Delta G = \Delta H - T \Delta S \] ### Step 1: Convert the temperature from Celsius to Kelvin The temperature given is 157°C. To convert this to Kelvin, we use the formula: ...

Dependence of Spontaneity on Temperature: For a process to be spontaneous , at constant temperature and pressure , there must be decrease in free energy of the system in the direction of the process , i.e. DeltaG_(P.T) lt 0. DeltaG_(P.T) =0 implies the equilibrium condition and DeltaG_(P.T) gt 0 corresponds to non- spontaneity. Gibbs- Helmholtz equation relates the free energy change to the enthalpy and entropy changes of the process as : " "DeltaG_(P.T) = DeltaH-TDeltaS" ""..."(1) The magnitude of DeltaH does not change much with the change in temperature but the entropy factor TDeltaS change appreciably . Thus, spontaneity of a process depends very much on temperature. For endothermic process, both DeltaH and DeltaS are positive . The energy factor, the first factor of equation, opposes the spontaneity whereas entorpy factor favours it. At low temperature the favourable factor TDeltaS will be small and may be less than DeltaH, DeltaG will have positive value indicated the nonspontaneity of the process. On raising temperature , the factor TDeltaS Increases appreciably and when it exceeds DeltaH, DeltaG would become negative and the process would be spontaneous . For an expthermic process, both DeltaH and DeltaS would be negative . In this case the first factor of eq.1 favours the spontaneity whereas the second factor opposes it. At high temperature , when T DeltaS gt DeltaH, DeltaG will have positive value, showing thereby the non-spontaneity fo the process . However , on decreasing temperature , the factor , TDeltaS decreases rapidly and when TDeltaS lt DeltaH, DeltaG becomes negative and the process occurs spontaneously. Thus , an exothermic process may be spontaneous at low temperature and non-spontaneous at high temperature. A reaction has a value of DeltaH =-40 Kcal at 400 k cal mol^(-1) . The reaction is spontaneous, below this temperature , it is not . The values fo DeltaG and DeltaS at 400 k are respectively

In a reaction DeltaG and DeltaH both are positive. The reaction would not be spontaneous if :

Gibbs-Helmoholtz equation relates the free energy change to the enthalpy and entropy changes of the process as (DeltaG)_(PT) = DeltaH - T DeltaS The magnitude of DeltaH does not change much with the change in temperature but the enrgy factor T DeltaS changes appreciably. Thus, spontaneity of a process depends very much on temperature. A reaction has value of DeltaH - 20 kcal at 200K , the reaction is spontaneous, below this temperature, it is not. the values DeltaG and DeltaS at 400K are, respectively

(A) All exothermic reactions are spontaneous at room temperature. ltBrgt (R) DeltaG=-ve for above reactions and for spontaneous reactions DeltaG=-ve .

Calculate the minimum temperature required for a reaction to be spontaneous if DeltaS = 27J/mol and DeltaH = 80KJ/mol

Assertion : Many endothermic reactions which are non- spontaneous on increasing the temperature. Reason : Endothermic reactions become spontaneous at high temperature if DeltaS is +ve and TDeltaS gt DeltaH .

What are the signs of DeltaH^(@) and DeltaS^(@) for a reaction that is spontaneous at all temperature?
