Calculate the activation energy for the following electrochemical reaction: 2H₂O(l) → O₂(g) + 4H⁺(aq) + 4e⁻ if the half-cell potentials are: E°(O₂/H₂O) = 1.23 V E°(H⁺/H₂) = 0 V Assuming the reaction follows Arrhenius equation, where the rate constant k is related to the activation energy Ea, temperature T and pre-exponential factor A by: k = A exp(-Ea/RT) where R is the gas constant equal to 8.314 J/molK.

A chemistry student wants to analyze a sample of wastewater from a local factory. They want to know the concentration of the pollutants from the wastewater before releasing it into the environment. The sample is collected in a 500 mL container. After performing the required tests, the student determines that the total dissolved solids (TDS) in the sample are 750 mg/L, and the concentration of NaCl in the sample is 150 mg/L. Calculate the mass of TDS and NaCl in the sample.
