4. Ethanol can be produced industrially using ethene gas and steam. The equation for the reaction is: C2H4(g) + H2O(g) = C2H50H(g) AH= -49kJmol-1 Although a high pressure and low temperature should produce the highest yield, this reaction is usually carried out under the compromise conditions of: pressure of 7Mpa temperature 3000C phosphoric acid (H3PO4) catalyst a. Use Le Chatelier's principle to explain why a high pressure is used to achieve a high yield in this process. b. Use Le Chatelier's principle to justify the use of the compromise temperature and catalyst in this process.

5.6. The following is a reaction with its initial conditions (amounts of each substance): Determine if of reacts to make products. Is it possible for to equal in this case? Why or why not?
Consider the reaction H2(g)+Br2(g)2HBr(g) where H = 103.8 kJ/mol. In a particular experiment, equal moles of H2(g) at 1.00 atm and Br2(g) at 1.00 atm were mixed in a 1.00-L flask at 25C and allowed to reach equilibrium. Then the molecules of H2 at equilibrium were counted using a very sensitive technique, and 1.10 1013 molecules were found. For this reaction, calculate the values of K, G, and S.
The reaction between magnesium metal and water (l) produces solid magnesium hydroxide and hydrogen gas. Calculate G for the formation of one mole of Mg(OH)2 at 27C and at 39C.
Monochloroethane (C2H5Cl) can be produced by the direct reaction of ethane gas (C2H6) with chlorine gas or by the reaction of ethylene gas (C2H4) with hydrogen chloride gas. The second reaction gives almost a 100% yield of pure C2H5Cl at a rapid rate without catalysis. The first method requires light as an energy source or the reaction would not occur. Yet G for the first reaction is considerably more negative than G for the second reaction. Explain how this can be so.
Biological standard states include specifying a reference temperature of 37.0C rather than the common reference temperature of 25.0C. For a chemical reaction in which H=24.3kJ see equation 2.62, by what percent does K change?
Reword the statement in Question 109 so that it is always true. Criticize this statement: Provided it occurs at an appreciable rate, any chemical reaction for which rG 0 will proceed until all reactants have been converted toproducts.
Consider the reaction CO(g)+H2O(g)CO2(g)+H2(g) Use the appropriate tables to calculate (a) G at 552C (b) K at 552C
Calculate H when a 38-g sample of glucose, C6H12O6(s), burns in excess O2(g) to form CO2(g) and H2O() in a reaction at constant pressure and 298.15 K.
Indicate whether each statement below is true or false. If a statement is false, rewrite it to produce a closely related statement that is true. For a given reaction, the magnitude of the equilibrium constant is independent of temperature. If there is an increase in entropy and a decrease in enthalpy when reactants in their standard states are converted to products in their standard states, the equilibrium constant for the reaction must be negative. The equilibrium constant for the reverse of a reaction is the reciprocal of the equilibrium constant for the reaction itself. For the reaction H2O2(ℓ) ⇌ H2O(ℓ) + O2(g) the equilibrium constant is one half the magnitude of the equilibrium constant for the reaction 2H2O2(ℓ) ⇌ 2H2O(ℓ) + O2(g)
