Here's a precise problem for a chemistry student to solve:Using Hess's Law, calculate the enthalpy change for the reaction where 2 moles of methane (CH4) reacts with 4 moles of oxygen gas (O2) to form 2 moles of carbon dioxide (CO2) and 4 moles of water (H2O), given the following known enthalpy changes:ΔH1 = -890 kJ/mol for the reaction: CH4 + 2O2 → CO2 + 2H2OΔH2 = -394 kJ/mol for the reaction: C + O2 → CO2ΔH3 = -286 kJ/mol for the reaction: H2 + (1/2)O2 → H2O

A student needs to calculate the Tafel slopes for the anodic and cathodic reactions from a given set of experimental data obtained during an electrochemical experiment. The experiment involves the corrosion of iron in a solution with a pH of 3.5. The anodic and cathodic current densities were measured at various applied potentials ranging from -700 mV vs SHE to -400 mV vs SHE. The student needs to plot a Tafel plot for each reaction and calculate their corresponding Tafel slopes. Based on the obtained results, the student needs to explain the corrosion mechanism of iron in the given acidic solution.
