What is the activation energy for a reaction if its rate constant is found to triple when the temperature is raised from 300 k to 310 k.
an optically pure compound was diluted to 200.0 mL with water and placed in a polarimeter tube 10.0 cm long. The measured rotation was -2.53° at 25 °C. Calculate the specific rotation of the compound.
The answer to Kinetics, The symmetry factor Beta was determined to be 0.4 for an activation controlled Ag deposition process. At overpotential n = -0.400 V the current density was found to be j = -5.125 A/dm^2.
