I was confused with the question I have to do as you didn't
mention anything about question. And in such a situations we need
to solve only first question. So I have done only first
question.

Identify correct statements pertaining to reaction energies. The rate of a reaction depends on the energy change between reactants and products. If Ke 1, the equilibrium will favor the reactants. If AG 0, Kg will be greater than 1. The reaction step with the highest energy transition state is called the rate determining step.

When a graph of energy vs, reaction progress was graphed for the reaction A + B rightarrow C + D, the following data was obtained: a) Draw a rough sketch of what this activation energy diagram looks like. Make sure axes and points are labeled appropriately. B) What is the numerical value of the activation energy obtained from the graph? c) Are reactants or products more stable? d) Is the reaction endothermic or exothermic? Explain. d) On the graph you...

In the plot of binding energy per nucleon versus mass number, you will note that the plot peaks around A 60. Nuclei below and above this value have a smaller binding energy. To prove this point determine the binding energy (in MeV) of 28 Ni, 626Fe with an A number of one less than 628Ni, and 639Cu with an A number of one greater than 638 Ni. (Let the mass of a proton be 1.0078 u, the mass of a...
