Calculate the enthalpy change (in kJ/mol) for the isomerization reaction of butene-1 to butene-2. Given the standard enthalpy of formation values for butene-1 as -126.3 kJ/mol and butene-2 as -126.0 kJ/mol, and the heat of combustion values for butene-1 as -2670.0 kJ/mol and butene-2 as -2666.0 kJ/mol.

A student wishes to determine the power output of an electrochemical cell that utilizes a half-reaction of copper oxide reducing to copper and a half-reaction of zinc oxidizing to zinc ions. The initial concentrations of the copper and zinc ions in the cell are 1.00 M and 0.10 M, respectively. The cell operates for 60 minutes at a constant rate of 0.200 A. Given that the standard cell potential is 1.10 V, calculate the power output of the electrochemical cell.
