Consider the reaction and potential energy diagram below: \[ \frac{\mathrm{A}+\mathrm{B}}{\text { Reactants }} \rightarrow \text { Products } \] What label best represents the activation energy of the reverse reaction? What label best represents the activation energy of the revel \[ X+Y \] Consider the following hypothetical reaction: \[ a A+b B \rightarrow x X+y Y \] Which equation correctly represents the equation to determine the value of the standard enthalpy of the reaction? \[ \begin{array}{l} {\left[x \Delta H^{\circ}(X)+y \Delta H^{\circ}(Y)\right]-\left[a \Delta H^{\circ}(A)+b \Delta H^{\circ}(B)\right]} \\ {\left[x \Delta H^{\circ}(X)-y \Delta H^{\circ}(Y)\right]-\left[a \Delta H^{\circ}(A)-b \Delta H^{\circ}(B)\right]} \\ {\left[x \Delta H^{\circ}(X)+y \Delta H^{\circ}(Y)\right]+\left[a \Delta H^{\circ}(A)+b \Delta H^{\circ}(B)\right]} \\ {\left[a \Delta H^{\circ}(A)-b \Delta H^{\circ}(B)\right]-\left[x \Delta H^{\circ}(X)+y \Delta H^{\circ}(Y)\right]} \end{array} \] For the reaction \( 2 \mathrm{NO}(\mathrm{g})+\mathrm{H}_{2}(\mathrm{~g}) \rightarrow \mathrm{N}_{2} \mathrm{O}(\mathrm{g})+\mathrm{H}_{2} \mathrm{O}(\mathrm{g}) \) the following data was obtained at a given temperature. Analyze the table of data carefully. (M/s) a) Determine the rate law constant, \( K \). b) Determine the complete, rate law ecuation. b) What is the rate of reaction when \( [\mathrm{NO}]=0.018 \mathrm{~mol} / \mathrm{L} \) and \( \left[\mathrm{H}_{2}\right]=0.036 \mathrm{~mol} / \mathrm{L} \) ?
