Expert Solution

Step 1: Determine the standard enthalpy of formation from the given data:

Given,

(i) The reaction:

$2 space C O subscript left parenthesis g right parenthesis end subscript space plus space 2 space N O subscript left parenthesis g right parenthesis end subscript space rightwards arrow space 2 space C O subscript 2 space left parenthesis g right parenthesis end subscript space plus space N subscript 2 space left parenthesis g right parenthesis end subscript space space space space space space increment H to the power of o subscript r x n end subscript space equals negative 754.2 space k J$

species	$increment H subscript f to the power of o space left parenthesis space k J divided by m o l space right parenthesis$
CO_{2 (g)}	-393.5
N_2(g)	0.0
CO_(g)	-110.5

(ii) $F e subscript 2 O subscript 3 space left parenthesis s right parenthesis end subscript space plus space 2 space A l subscript left parenthesis s right parenthesis end subscript space rightwards arrow space A l subscript 2 O subscript 3 space left parenthesis s right parenthesis end subscript space plus space 2 space F e subscript left parenthesis s right parenthesis end subscript$

species	$increment H to the power of o subscript f space left parenthesis space k J divided by m o l space right parenthesis$
Fe₂O₃_(s)	-824.2
Al_(s)	0.0
Fe_(s)	0.0
