For a particular hypothetical reaction, A+B →2C, the value of AG° is -125 kJ/mol. What is the value of AG for this reaction at 35°C when [A] = 0.10 M, [B] = 0.05 M, and [C] = 2.0 × 10¹ M?

In an experiment, 74.3 g of metallic copper was heated to 100.0°C and then quickly dropped into 200.0 mL of water in a calorimeter. The heat capacity of the calorimeter with the water was 875 J/°C. The initial temperature of the calorimeter was 27.5°C, and the final temperature after addition of the metal was 29.8°C. What is the value of the molar heat capacity of copper?

The Haber-Bosch process permits the direct conversion of molecular nitrogen to ammonia, which can be used in large-scale fertilizer production. Given the balanced Haber-Bosch reaction and using the bond energies in the table below, estimate the enthalpy change associated with the reaction.

Benzoic acid is used to determine the heat capacity of bomb calorimeters because it can be obtained in pure form and its energy of combustion is known very accurately (−26.43 kJ/g). Determine the heat capacity of a calorimeter that had a temperature increase of 9.199°C when 3.500 g of benzoic acid was used.
