How does `T DeltaS` determine the spontaneity of process?

Text Solution

AI Generated Solution

To determine how \( T \Delta S \) influences the spontaneity of a process, we can analyze the relationship between Gibbs free energy (\( \Delta G \)), enthalpy (\( \Delta H \)), and entropy (\( \Delta S \)). Here’s a step-by-step breakdown: ### Step 1: Understanding the Gibbs Free Energy Equation The Gibbs free energy change for a process is given by the equation: \[ \Delta G = \Delta H - T \Delta S \] Where: ...

Define the term 'entropy'. How does TDeltaS determine the spontaneity of a process?

Assertion (A): The thermodynamic factor which determines the spontaneity of a process is the free energy. For a process to be spontaneous the free energy must be-ve. Reason (R ) : The change in free energy is related to the change in a process must always be positive if its is spontaneous.

The sole criterion for the spontaneity of a process is

What is entropy and how is it related to the spontaneity of a process?

For a spontaneous process :-

The change in Gibbs free energy of the system along provides a criterion for the spontaneity of a process at constant temperature and pressure. A change in the free energy of a sytem at constant temperature and pressure will be: DeltaG_("system") = DeltaH_("system") - T DeltaS_("system") For a spontaneous reaction DeltaG , equilibrium constant K and E_("cell")^(0) will be respectively:

The incorrect criterion for the spontaneity of a process is

What do you understand by the spontaneity of a process ? Discuss the spontaneity of a process in terms of entropy and free energy.

What is Gibbs free energy ? Derive the relation, Delta_G = DeltaH - T Delta S . Discuss the free energy criterion for the spontaneity of a process.

Discuss the effect of temperature on the spontaneity of a process when for the process both DeltaH and DeltaS are positive.
