≪Propose a reaction mechanism using the criteria presented in the lesson‚ with the third step as the rate-determining step. Hypothetical reaction: A + 2B + 4C ---> 2D + E The rate law has been determined to be [B]^1[C]^2≫ I had prepared the material below before I received your criteria. As you know‚ each step in a reaction mechanism is an elementary step. Each step is characterized by its molecularity. A step could be unimolecular‚ as in A → B or A → B + C It could be bimolecular as in 2A → B +

HEAT TRANSFER MECHANISMS Heat energy is being transferred from one location to another because of a temperature difference. The three mechanisms for heat transfer are: • Conduction. When you grip the hot handle of a pan on a stove‚ you feel conduction in action. Heat flows from the pan and along the length of the handle to its cooler free end. This is because one end of the rod is held at the high temperature‚ and the other end stays at the lower temperature. Although the rod itself doesn’t

It describes the dynamic equilibrium by which internal constancy is maintained within set limits by regulation and control. There are many examples of homeostatic control throughout the human body and in other living organisms‚ such as pH‚ pressure‚ and temperature. A concept important to homeostasis is the process of feedback circuits;
