The value of ΔH° for the reaction below is -482 kJ. Calculate the heat (kJ)released to the surroundings when 6.00 g of CO (g)reacts completely. 2CO (g)+ O₂ (g)→ 2CO₂ (g)

Question

Quizplus · Accepted Answer

To calculate the amount of heat released, we need to first find the amount of moles of CO that reacts completely.

Molar mass of CO = 12.01 + 15.99 = 28 g/mol

Number of moles of CO = 6.00 g / 28 g/mol = 0.214 mol

Now, we can use the given ΔH° value to calculate the heat released:

Heat released = ΔH° x moles of reactants

= -482 kJ/mol x 0.214 mol

= -103 kJ

Since the question asks for the amount of heat released to the surroundings, which is a positive value, we take the absolute value of our answer:

| -103 kJ | = 103 kJ

Therefore, the best choice is C, 51.6 kJ.

The Value of ΔH° for the Reaction Below Is -482
