For which of the following processes/reactions both enthalpy change as well as entropy change have +ve values?
Options:(select one or more)
Answer:
A, C, D
Solution:
A and D absorb heat for dissociation and there is an increase in number of moles of gases.
Hard boiling of egg involves breakage of intermolecular forces and hence is endothermic. As the higher order structures protein change to primary structure, there is an increase in entropy. Freezing of water is exothermic and has a negative entropy change of the system.
