there is mistake in the calculation. the second law states that in any spontaneous process there is an increase in the entropy of the universe.
there is mistake in the calculation. the second law states that in any spontaneous process the increase in the entropy of the system equals zero. also there is a decrease in entropy of the system, as in the present case, this decrease is canceled by an increase in entropy of the surroundings.
