In an isothermal process, the temperature remains constant, and for an ideal gas, the change in enthalpy is zero.

The change in entropy for an isothermal and reversible expansion of an ideal gas is given by ΔS = nR ln(V2/V1). For 1 mole, n = 1, hence ΔS = R ln(V2/V1).

The change in entropy for an isothermal expansion of an ideal gas is given by ΔS = nR ln(V2/V1). For 1 mole, it simplifies to ΔS = R ln(V2/V1).

Increasing temperature will make ΔG more negative for a reaction with a negative ΔH and positive ΔS, enhancing spontaneity.

For a reaction with ΔH > 0 and ΔS < 0, increasing temperature will make ΔG more positive, thus decreasing spontaneity.

Increasing temperature generally increases the kinetic energy of particles, leading to greater disorder and thus an increase in entropy.

Increasing temperature generally increases the entropy of a system as the molecular motion becomes more chaotic.

According to Le Chatelier's principle, increasing the temperature of an exothermic reaction shifts the equilibrium to the left, decreasing the equilibrium constant.

For an endothermic reaction, increasing the temperature increases the equilibrium constant.

As temperature increases, the kinetic energy of particles increases, leading to greater disorder and thus higher entropy.
