The free energy change of the reaction a(g) ⟺ b(g) is –32.5 kj under nonstandard conditions. the standard free energy change of the reaction is –42.5 kj. is the reaction at the nonstandard conditions more spontaneous or nonspontaneous? the reaction is more spontaneous at nonstandard conditions. the reaction is less spontaneous at nonstandard conditions. the reaction is at equilibrium.

One way in which the useful metal copper is produced is by dissolving the mineral azurite, which contains copper(ii) carbonate, in concentrated sulfuric acid. the sulfuric acid reacts with the copper(ii) carbonate to produce a blue solution of copper(ii) sulfate. scrap iron is then added to this solution, and pure copper metal precipitates out because of the following chemical reaction: (s) (aq) (s) (aq) suppose an industrial quality-control chemist analyzes a sample from a copper processing plant in the following way. he adds powdered iron to a copper(ii) sulfate sample from the plant until no more copper will precipitate. he then washes, dries, and weighs the precipitate, and finds that it has a mass of .

When 46 grams of water are produced how many grams of oxygen must react according to the equation 2h2+o2=2h2o

The reaction: (ch3)3cbr + oh− → (ch3)3coh + br− in a certain solvent is first order with respect to oh−. in several experiments, the rate constant k was determined at different temperatures. a plot of ln(k) vs 1/t was constructed and the slope of the line was -1.10 x 104 k with a y-intercept of 33.5. what is the value for k at a temperature of 25°c?
