Calculate the enthalpy change for the thermite reaction: 2Al(s)+Fe2O3(s)→2Fe(s)+Al2O3(s), ΔH∘rxn=−850 kJ when 12.0 mol of Al und
djverab [1.8K]

<u>Answer:</u> The enthalpy of the reaction for given amount of aluminium will be -51.0\times 10^2kJ

<u>Explanation:</u>

We are given:

Moles of aluminium = 12 moles

For the given chemical reaction:

2Al(s)+Fe_2O_3(s)\rightarrow 2Fe(s)+Al_2O_3(s);\Delta H^o_{rxn}=-850kJ

By Stoichiometry of the reaction:

If 2 moles of aluminium produces -850 kJ of energy.

Then, 12 moles of aluminium will produce = \frac{-850kJ}{2mol}\times 12mol=-5100kJ of energy.

Converting this into three significant figures, we get:

\Rightarrow -5100kJ=-51.0\times 10^{2}kJ

Thus, the enthalpy of the reaction for given amount of aluminium will be -51.0\times 10^2kJ
