Worksheet: Converting Enthalpy to Heat
In this worksheet, we will practice calculating an enthalpy change from tabulated enthalpies and converting this value to a temperature change.
The enzyme catalase catalyzes the decomposition of hydrogen peroxide by the following exothermic reaction
Suppose that a small amount of solid catalase is added to a 0.1 M aqueous solution of hydrogen peroxide in a calorimeter, with the initial temperature of the solution being . If all the heat liberated in the reaction is retained by the solution, what will be the final temperature of the solution after the reaction mixture has reached its final equilibrium state?
The heats of formation for and are and respectively. The heat capacity of the solution may be taken as 4.18 kJ/K⋅L.
Propane is a hydrocarbon that is commonly used as a fuel. The heat of combustion of propane is kJ/mol.
Which of the following is a balanced equation for the complete combustion of propane gas?
What volume of air at and 1.00 atmosphere is needed to completely combust 25.0 grams of propane? Assume that air is 21.0% by volume and all components of air are ideal gases.
What is the heat of formation, , of propane given that of = kJ/mol and of = kJ/mol?
If all of the heat released by burning 25.0 g of propane is transferred to 4.00 kg of water, how much does the temperature of the water increase? The specific heat capacity of water is 4.184 J/g⋅K.
