WebSign of Entropy Change: The sign of entropy change during a process tells about the change in randomness in the system. For example, when solid and liquid species get converted into gaseous species, the corresponding entropy change is positive, which means that the randomness increases. Answer and Explanation: WebTry to rationalize the sign of ΔS∘rxn in each case. Drag the appropriate items to their respective bins.
