A reaction occurs spontaneously if:
View answer and explanation
Correct option: B
T∆S>∆H and both ∆H and ∆S are positive
Option B (T∆S>∆H and both ∆H and ∆S are positive) is correct because for a reaction to be spontaneous, the change in Gibbs free energy (∆G) must be negative, which occurs when T∆S > ∆H, given that both ∆H and ∆S are positive.

The internal energy of one mole of a gas is:
An ideal gas is allowed to expand both reversibly and irreversibly in an isolated system. If is the initial temperature and is the final temperature, which of the following statements is correct?
For which of the process, ∆S is negative?
The work done by a weightless piston in causing an expansion ∆V (at constant temperature), when the opposing pressure, P is variable, is given by:
Assertion :- At constant pressure of the change work done is negative.
Reason :- During phase transition work done is always negative. For the reaction, at . Hence, is
