If a piece of Aluminum (specific heat capacity = 0.902 J/g · ºC) with a mass of 53.4574 g is heated to a temperature of 97.6 ºC, and then transferred to a calorimeter that contains 75.9809g of water at 21.5 ºC (specific heat capacity = 4.184 J/g · ºC ) what is the final temperature of the system (Tf) after it reaches thermal equilibrium?

A 1.000 g sample of octane (C8H18) is burned in a bomb calorimeter containing 1200 grams of water at an initial temperature of 25.00ºC. After the reaction, the final temperature of the water is 33.20ºC. The heat capacity of the calorimeter (also known as the “calorimeter constant”) is 837 J/ºC. The specific heat of water is 4.184 J/g ºC. Calculate the heat of combustion of octane in kJ/mol.

A chemical reaction is carried out in a calorimeter with the following heat capacity (C = 224.7 J/ºC). The reaction occurs in 34.3 g of water. The initial temperature before the reaction is 29.4 ºC and the final temperature after the reaction is 61.8 ºC. The temperature change is the same for the water as it is for the calorimeter. What is the energy change for the reaction (qrxn) in kJ?

1. A substance decomposes in a first-order reaction with a rate constant of 6.70 x 10–4 s –1 . If the initial concentration of the substance is 1.50 M, what is its concentration after 500. s?
