Problem

Carbon monoxide and oxygen react according to

2\,\text{CO}(g) + \text{O}_2(g) \longrightarrow 2\,\text{CO}_2(g)

with

\Delta H = -566\;\text{kJ}

for the reaction as written. A rigid steel vessel is charged with

2.50\,\text{mol}

of CO and

1.00\,\text{mol}

O_2

and the reaction proceeds to completion at constant pressure. (a) Identify the limiting reactant, supporting your answer with stoichiometric reasoning. (b) Calculate the number of moles of

CO_2

produced when the reaction reaches completion. (c) Determine the total heat released, in kilojoules, for the reaction carried out in the vessel. (d) Due to insulation inefficiencies, only

60\%

of the heat released in part (c) is transferred to the surroundings. Calculate the quantity of heat actually transferred to the surroundings and state its sign.
