Do the magnitudes of these thermodynamic parameters match what you expect for a cycloaddition reaction? Explain

What is the enthalpy of combustion of ethane, C,H,, in kilojoules per mole of ethane? STRATEGY 1. Write the balanced chemical equation for the reaction. 2. Using the coefficients from the balanced equation, calculate AHn- 3. Scale the heat of reaction to be per mole of ethane. 4. Convert the heat released from kilojoules per mole to kilojoules per gram. Steps 1 and 2: The balanced chemical equation and AHn are given here. 2C,H,(g) + 70,(g) → 4 CO,(g) + 6 H,O(1) AHn = -3120.8 kJ Step 3: This amount of heat, 3120.8 kJ, is released per 2 mol of ethane according to the balanced chemical equation. How much heat is released when just one mole of ethane is burned? heat released: kJ -C,H, mol

tml?ClassID=543616615# Calculate the enthalpy, in kJ/mol, for the combustion of the hydrocarbon from the data from the previous steps. 9cal = 6191.78 J n= 0.0019243682 mol AH = [ ? ] kJ/mol Enter either a + or - sign AND the magnitude. Give your answer to three significant figures. AH (kJ/mol) Enter

The lower the change in free enthalpy associated with a reaction, the slower this reaction is. True False
