A student is given a lead-acid battery, which has a standard reduction potential of -0.356 V. The battery is undergoing a reaction where Pb(s) + SO4^2-(aq) -> PbSO4(s) + 2e^-. If the concentration of PbSO4 in the anode compartment is 1.15 M and the concentration of PbSO4 in the cathode compartment is 0.55 M, what is the power output of the battery, assuming it has a current of 1.25 A?

A chemistry student wants to investigate the adsorption behavior of a gas on a solid surface. Using the Langmuir adsorption isotherm, determine the maximum adsorption capacity of the surface and the equilibrium constant, if the surface area of the solid is 10 cm$^2$ and the gas pressure is varied from 0.1 to 1 bar at a constant temperature of 298 K.
