How much heat will be released when 0.750 moles of carbon monoxide (CO) react in an excess of oxygen gas? 2CO (g) + O2 (g) → 2CO2 (g) + 566 kJ

A. 566 kJ

B. 424 kJ

C. 212 kJ

D. 755 kJ

From the given chemical reaction, it is said that when 2 moles of carbon dioxide reacts with 1 mole of oxygen gas, it yields 2 moles of carbon dioxide and a 566 kJ of work released.

We can conclude that heat released when 0.750 moles of carbon monoxide reacts will be:

566 kJ / 0.750 moles = 754.67 kJ

Therefore, there will be 754.67 kJ of heat released when 0.750 moles of carbon monoxide (CO) react in an excess of oxygen gas.

The correct answer is 212kJ
