If the activation energy for the decomposition of a compound is 99.1 Kj/mol, at what temperature will the rate be 10 percent greater than its rate at 25C?
One of the reasons that back titration is preferred to direct titration is because of the limited solubility of carbonates in water. Why does this make direct titration difficult and why does back titration tend ot circumvent this difficulty
