Answer: Reaction one is more thermodynamically
feasible at standard conditions. For a reaction to be
thermodynamically feasible 
should be negative. For this 
(entropy) must be negative. As can be seen in the first reaction
two of the reacting molecules react to form one molecule of ethanol
it means degree of randomness decreases and hence entropy
decreases. This makes the reaction more feasible.

Consider the following reactions at some temperature: 2NOCI(g) � 2NO(g) + Cl2 (g) K = 1.6 X 10-5 2NO(g) � N2 (g) + 02 (g) K = 1 X 1031 For each reaction, assume some quantities of the reactants were placed in separate containers and allowed to come to equilibrium. Describe the relative amounts of reactants and products that would be present at equilibrium. At equilibrium, which is faster, the forward or reverse reaction in each case?

Consider " 2 S2O32-". Which of the following statements is FALSE? There are 3 O atoms contained in each unit. There are 4 S atoms contained in two units. Each unit of S2032 has a ratio of 1 S: 1.5 O Two units of S2032 have an overall charge of -4. 10 atoms are all connected together.The chemical equation H2 (3)+ O2 (3)>H2O (3) is not balanced.

1. For the following reactions, determine the products when two solutions are mixed. Use the solubility rules to predict whether a precipitate would form. If no reaction occurs, write "NR”. Be sure to balance your reaction and include all states of matter. The first one has been done for you. a) 3 Ba(NO3)2 (aq) + Al2(SO4)3 (aq) → 2 AI(NO3)3 (aq) + 3 BaSO4 (s) b) LINO3(aq) + Mg(C2H302)2 (aq) → c) NiSO4 (aq) + K3PO4 (aq) → d) Na2S...

Problem 2: I told you it would show up again! (8 pts) Consider two different 500 ml vessels, each crammed with 1 mole of gas at 500 K. In one vessel, the gas is water, H20. In the other vessel is ethane, C2H6. Notably, these two gases are special: the van der Waal's parameter value for a is roughly the same as each: a = 5.54 L2 bar/ mol? (water), 0 = 5.56 L bar/mol (ethane). Because a is the...

1.Calculate the free energy(ΔG°)of the following reactions: a)H2(g) + O2(g)→ H2O2(g) b)H2O2(g) + H2(g) → 2 H2O (g) How do the free energy values for these two reactions compare to the free energy of the combustion of hydrogen gas? Hint: (ΔG) is a state function, therefore Hess’s law is applicable.The combustion of hydrogen gas is modeled by the overall equation is 2 H2(g) + O2(g)→ 2 H2O(g). 2.Based on your calculations in the previous question and your understanding of reaction...
