10.85 Iodine is not very soluble in water, but it dissolves readily in a solution containing iodide ions by the following reaction: I2(aq)+I(aq)I3(aq) The following graph shows the results of a study of the temperature dependence of G for this reaction. (The solid line is a best fit to the actual data points.) Notice that the quantity on the y axis is G/T , not just G. Additional data relevant to this reaction are also given in the table that follows the graph. (a) Calculate G for this reaction at 298 K. (DO NOT read this value off the graph. Use the data given to calculate a more accurate value.) (b) Determine H for this reaction. Assume that H is independent of T. (HINT: You will need to use the graph provided to find H . It may help if you realize that the graph is a straight line and then try to write an equation for that line
9.20 State the first law of thermodynamics briefly in your own words.
One statement of the second law of thermodynamics is that heat cannot be turned completely into work. Another is that the entropy of the universe always increases. How are these two statements related?
Some water is placed in a coffee-cup calorimeter. When 1.0 g of an ionic solid is added, the temperature of the solution increases from 21.5C to 24.2C as the solid dissolves. For the dissolving process, what are the signs for Ssys, Ssurr, and Suniv?
Nickel metal reacts with carbon monoxide to form tetra-carbonyl nickel, Ni(CO)4: Ni(s)+4CO(g)Ni(CO)4(g) This reaction is exploited in the Mond process in order to separate pure nickel from other metals. The reaction above separates nickel from impurities by dissolving it into the gas phase. Conditions are then changed so that the reaction runs in the opposite direction to recover the purified metal. (a) Predict the sign of S for the reaction as written above. (b) Use tabulated thermodynamic data to calculate H, S , and G for the reaction. (c) Find the range of temperatures at which this reaction is spontaneous in the forward direction.
A wad of steel wool (specific heat=0.45J/gC) at 25C is misplaced in a microwave oven, which later is accidentally turned on high. The oven generates microwaves of 13.5 cm wavelength at the rate of 925 moles of those photons per second. All of the photons are converted to high-heat energy, raising the temperature of the steel wool. Steel wool reacts explosively with the oxygen in the oven when the steel wool reaches 400.0C. If the steel wool explodes after 1.55 seconds, how many grams of steel wool were accidentally put into the oven?
Thermodynamics provides a way to interpret everyday occurrences. If you live in northern climates, one common experience is that during early winter, snow falls but then melts when it hits the ground. Both the formation and the melting happen spontaneously. How can thermodynamics explain both of these seemingly opposed events?
