1. The standard enthalpy of formation for rhodium dichromate is $$450\mathrm{kJ}/\mathrm{mol}$$. Write the thermochemical equation in two different ways. Use diagrams to explain energy changes in reactions 2. Draw a fully labelled, potential energy diagram for the reaction in question 1. Performs calorimetry calculations for energy changes of reactions 3. In a coffee cup calorimeter, $$284.9\mathrm{mL}$$ of $$0.921\mathrm{mol}/\mathrm{L}$$ sodium nitrate is mixed with $$646.3\mathrm{mL}$$ of $$0.923$$ mol/L sulfuric acid, both originally at $$18.42^{?}\mathrm{C}$$. The temperature drops to $$16.12^{?}\mathrm{C}$$. Determine the molar enthalpy for sodium nitrate. Analyze enthalpy changes of reactions using Hess' Law
