During a spontaneous chemical reaction, it is found that δssys is less than 0. this means that group of answer choices δssurr is less than 0 and its magnitude is less than δssys. δssurr is less than 0 and its magnitude is greater than δssys. δssurr is greater than 0 and its magnitude is less than δssys. δssurr is greater than 0 and its magnitude is greater than δssys. an error has been made, as ssys is greater than 0 by necessity for a spontaneous process.

The correct option is: ΔSsurr is greater than 0 and its magnitude is greater than ΔSsys.  

Explanation:

For a chemical reaction to be spontaneous, the change in the Gibbs free energy should be negative (ΔG = -ve).

At constant temperature (T) and pressure, the Gibbs free energy is given by the equation:

Here, is the enthalpy change and is the entropy change of the system.

Also, according to the second law of thermodynamics, for a spontaneous process, the total entropy,

Therefore, for a reaction to be spontaneous, if is less than 0 or negative; then should be greater than 0 or positive. Also, > .
