The molecular diffusion coefficient of methanol dissolved in liquid water as the solvent is 1.28 X 10^-5 cm²/s at 15 C and 1.0 atm total system pressure. What is the molecular diffusion coefficient for methanol dissolved in liquid water at 30 C? Potentially useful data: for methanol (A), liquid viscosity μ_A = 0.61 cP at 15 C, μ_A = 0.51 cP at 30 C, M_A = 32 g/gmole; for water (B), liquid viscosity μ_B = 1.14 cP at 15 °C, μ_B = 0.797 cP at 30 C, M_B = 18 g/g mole.
