Q2. The etching of semiconductors in the manufacture of computer chips is another solid- liquid dissolution reaction. The rate of dissolution was found to be a function of the reacting liquid solution redox potential relative to the energy level conduction band of the semiconductor. It was found that the reaction rate could be increased by a factor of 1095 simply by changing the anion of acid. From the data below determine the reaction order and specific reaction rate for the dissolution of MnO2 in HBR. Use least square analysis method. Do it by both hand calculations and Excel and compare your answer 4.0 CAO 0.1 -TA(mol HBr/m2.h) 0.073 0.5 0.7 1.0 1.84 2.0 4.86 12.84 |
