**Heat of Formation**

Use a standard enthalpies of formation table to determine the change in enthalpy for each of these reactions.

a) $\text{NaOH(s)} + \text{HCl(g)} \rightarrow \text{NaCl(s)} + \text{H}_2\text{O(g)}$

b) $2 \text{CO(g)} + \text{O}_2\text{(g)} \rightarrow 2 \text{CO}_2\text{(g)}$

c) $\text{CH}_4\text{(g)} + 2 \text{O}_2\text{(g)} \rightarrow \text{CO}_2\text{(g)} + 2 \text{H}_2\text{O(l)}$

d) $2 \text{H}_2\text{S(g)} + 3 \text{O}_2\text{(g)} \rightarrow 2 \text{H}_2\text{O(l)} + 2 \text{SO}_2\text{(g)}$

e) $2 \text{NO(g)} + \text{O}_2\text{(g)} \rightarrow 2 \text{NO}_2\text{(g)}$

**Standard Enthalpies of Formation ($ \Delta H_f $)**

Expert Solution

Step 1: Introduction to the change in standard enthalpy of the reaction

The change in standard enthalpy of the reaction is given by

$capital delta H degree subscript r x n end subscript equals sum n subscript p cross times capital delta H degree subscript f left parenthesis p r o d u c t s right parenthesis minus sum n subscript r cross times capital delta H degree subscript f left parenthesis r e a c tan t s right parenthesis$

n_p = represents the stoichiometric coefficients of the products,

n_r= represents the stoichiometric coefficients of thereactants

$capital delta H degree subscript f$ = represents the standard enthalpies of formation
