Question

Consider the following cell reaction: al(s)|al3 (aq)||br2(l)|br-(aq) 13al(s) 12br2(l)����13al3 (aq) br-(aq)��rh��=-299 kj/mol br2(l) 2e-����2br-(aq)e��=1.09v. What is the standard enthalpy change (��H��) for the reaction?

Answer 1

The standard enthalpy change for the reaction can be calculated using the formula ΔH° = Σ(νproductsΔHf, products) - Σ(νreactantsΔHf, reactants).

Step-by-step explanation:

The standard enthalpy change for this reaction can be calculated using the formula:

ΔH° = Σ(νproductsΔHf, products) - Σ(νreactantsΔHf, reactants)

Where ΔH° is the standard enthalpy change, ν represents the stoichiometric coefficients of the reactants and products, and ΔHf is the standard enthalpy of formation. By substituting the given values in the equation, we can calculate the standard enthalpy change for the reaction.
