Question 2 • Foothill-B Period-Chemistry-26/27B
Which equation should be used to calculate Hrxn for this reaction?
Answer
A
(-393.5kJ/mol + (-285.83 kJ/mol))-(-1,273.02 kJ/mol)B
-1,273.02 kJ/mol - ((6 mol)(-393.5 kJ/mol) + (6 mol)(-285.83 kJ/mol))C
((6 mol)(-393.5 kJ/mol) + (6 mol)(-285.83 kJ/mol)) - (1 mol)(-1,273.02 kJ/mol)
