SO2 + NO2 ⇌ SO3 + NO 5.1.1 Write out the Kc expression for this reaction? (2) 5.1.2 Calculate the equilibrium constant at this temperature if the moles of NO(g) at equilibrium is found to be 0,02. (5) 5.2 Consider the equilibrium between the hydrogen sulfate ion and water: HSO4 – (aq) + H2O(l) ⇌ SO4 2- (aq) + H3O+ (aq) 5.2.1 When the temperature is decreased, the pH of the solution decreases. Use this information to deduce whether the forward reaction is exothermic or endothermic. Explain according to Le Chatelier’s Principle. (4) 5.2.2 Calculate the concentration of OH- ions in the aqueous equilibrium mixture if the concentration of H3O+ ions at 25˚C is 2,5 x 10-3 mol.dm-3. (3) 5.3 Consider the reaction in a closed system: H2(g) + I2(g) ⇌ 2HI(g) (

Reаd the pаssаge and then chооse the best answer tо the question. Answer the question based on what is stated or implied in the passage. Unemployment was the overriding fact of life when Franklin D. Roosevelt became president of the United States on March 4, 1933. At the time, the government did not systematically collect statistics of joblessness; actually it did not start doing so until 1940. The Bureau of Labor Statistics later estimated that 12,830,000 persons were out of work in 1933, about one-fourth of a civilian labor force of more than 51 million. Roosevelt signed the Federal Emergency Relief Act on May 12, 1933. The president selected Harry L. Hopkins, who headed the New York relief program, to run FERA. A gifted administrator, Hopkins quickly put the program into high gear. He gathered a small staff in Washington and brought the state relief organizations into the FERA system. While the agency tried to provide all the necessities, food came first. City dwellers usually got an allowance for fuel, and rent for one month was provided in case of eviction. This passage is primarily about
