Determine the amount of heat (in kJ) given off when 1.72 * 10^4 g of NO2 is produced according to the following equation
2NO + O2 --> 2 NO2 H = - 114.6 kJ/mol
According to your equation, when 1 mole of NO2 is produced, 114.6kJ of energy is given off.
What is the mass of 1 mole of NO2?
That mass will give the amount of energy given, that is 144.5kJ
What mass are you required to find the energy released?
By proportion, you will obtain your required answer!
Hope it helped. Post back to confirm your answer.
