how does activation energy affect kinetic energy? Why is it that you neglect the activation energy of the forward reaction? When oversimplified Eafwd is So Small thot we eglect it Fa Potential energy Reaction coordinate +G +heat + Bo Energy
Question 35 (1 point) The relationship between the activation energy of the forward and reverse reactions is related by the energy difference between the reactants and products. If the reactants are higher in energy than the products, the activation energy for the forward reaction will be smaller than the activation energy for the reverse reaction and vice versa True False Question 36 (1 point) A catalyst is a substance that is not used up during a reaction. It also does...
During free fall, how does weight affect kinetic energy, gravitational potential energy, and total energy? (neglecting air resistance) How would this change between a basketball and a beach ball?
(a) How can you manipulate the size of activation barrier we discussed today? Describe by discussing Figure 3.8. (b) If you apply voltage “X” then by what amount forward and backward activation energy barrier will decrease. (c) What is transfer coefficient “α” and how it is connected with the barrier shape? Figure 3.8 If the Galvani potential across a reaction interface is reduced, the free energy of the forward reaction will be favored over the reverse reaction. While the chemical...
2. Suppose that you are asked to find the reaction energy and activation energy of a tautomerization reaction A → B. It is known that B is less stable than A. (60) EN-NH₂ NH2 OH so a. How will you do it? Draw the potential energy profile. In the profile, what do you think the reaction coordinate is? Draw the approximate structure of the transition state geometry. Explain the reason. Send the .gzmat of the approximate transition state structure via...
Draw a labelled reaction coordinate diagram for the both SN reactions. Label the activation energy (free energy of activation) and give the approximate structures of the intimal state, the transition states, the intermediate and product at the correct points along the reaction coordinate. Also, can you decide on the basis of the kinetic expression whether the t-butyl chloride-hydroxide ion reaction proceeds by a one-step or a two-step mechanism? Explain why observed kinetic expression is consistent with the mechanism you chose.

What are some examples of real-world things that follow a Boltzmann distribution? How does activation energy affect this process?
Shown below is the formation reaction of ammonia. How does the catalyst used in the industrial production of ammonia affect the activation energies of the forward and reverse reactions? N2+3H2⇌2NH3 A. activation energy decreased for the forward reaction, increased for the reverse reaction B. activation energy increased for the forward reaction, decreased for the reverse reaction C. activation energy decreased both the forward and reverse reactions D. activation energy increased for both the forward and reverse reactions
Question 12 How does an enzyme work to catalyze a reaction? -It lowers the activation energy of a reaction. -It raises the temperature of a reaction. -It supplies the energy to speed up a reaction. -It increases the concentration of the reactants in a reaction. -It allows the reaction to proceed through different intermediates.
