Unit of entropy is

1. JK⁻¹ mol⁻¹
2. J mol⁻¹
3. J⁻¹ K⁻¹ mol⁻¹
4. JK mol⁻¹

Correct answer: JK⁻¹ mol⁻¹

Solution

Entropy is defined as the measure of randomness or disorder in a system, and its unit is derived from the formula ΔS = ΔQ/T, where heat (Q) is in joules and temperature (T) is in kelvin, giving the unit JK⁻¹ mol⁻¹.
