Calculating reaction free energy under nonstandard conditions
A chemist fills a reaction vessel with 0.969 atm nitrogen (N₂) gas, 6.95 atm oxygen (O₂) gas, and 4.48 atm nitrogen monoxide (NO) gas at a temperature of
25.0°C.
Under these conditions, calculate the reaction free energy AG for the following chemical reaction:
N₂(g) + O₂(g) 2NO(g)
Use the thermodynamic information in the ALEKS Data tab. Round your answer to the nearest kilojoule.

A chemical engineer is studying the two reactions shown in the table below.
In each case, he fills a reaction vessel with some mixture of the reactants and products at a constant temperature of 53.0 °C and constant total pressure. Then,
he measures the reaction enthalpy AH and reaction entropy AS of the first reaction, and the reaction enthalpy AH and reaction free energy AG of the second
reaction. The results of his measurements are shown in the table.
Complete the table. That is, calculate AG for the first reaction and AS for the second. (Round your answer to zero decimal places.) Then, decide whether, under

A chemistry student must write down in her lab notebook the concentration of a solution of potassium chloride. The concentration of a solution equals the mass
of what's dissolved divided by the total volume of the solution.
Here's how the student prepared the solution:
. The label on the graduated cylinder says:
empty weight: 1.05 g
. She put some solid potassium chloride into the graduated cylinder and weighed it. With the potassium chloride added, the cylinder weighed 84.7 g.
• She added water to the graduated cylinder and dissolved the potassium chloride completely. Then she read the total volume of the solution from the
markings on the graduated cylinder. The total volume of the solution was 198.62 mL.
What concentration should the student write…
