Answer #1

Entropy Change of the universe is the sum of Entropy change of System plus the Entropy change of the surroundings. And acoording to the 2nd law of thermodynamics Entropy change of universe for any process is either +ve or zero (for reversible processes). Though for a given system it may be +ve ,-ve or zero.

Entropy generation accounts for the irreversibilty in a process , greater the deviation from reversibility, greater the entropy generation.Hence for a given system Entropy genearation can be +ve (Irreversible prpcess) or zero (Reversible process) and can never be -ve.

Calculate the entropy change of the UNIVERSE when 2.054 moles of N2O(g) react under standard conditions at 298.15 K. Consider the reaction N2O(g) + 3H2O(l)2NH3(g) + 2O2(g) for which H° = 683.1 kJ and S° = 365.6 J/K at 298.15 K. Is this reaction reactant or product favored under standard conditions? If the reaction is product favored, is it enthalpy favored, entropy favored, or favored by both enthalpy and entropy? If the reaction is reactant favored, choose 'reactant favored'.

Living organisms are highly structured, and therefore much lower in entropy than the substances from which they grow. How is it possible that these (local) entropy decreases can occur? a) The Earth re-emits as much energy as it absorbs while keeping the same temperature, so the change in heat is zero, making the change in entropy of the Earth zero. b) The entropy of one part of the universe can decrease provided the total entropy of the universe increases. Energy...
