Select all the correct answer(s) and explanation(s) for the following statement:

The transition state has a higher free energy than the substrate but not the product.

a. True, because the free-energy difference between the reactants and substrates accounts for the equilibrium of a reaction.
b. False, especially when the product is unstable; in this case, the product will have higher free energy than the substrate and the transition state.
c. While the statement is false, the given reasons for it being false are incorrect.
d. True, because the formation of transition state does not factor in the energy that is released when the transition state becomes a product.
e. False, because the transition state is a short-lived molecular structure that is no longer the substrate but is not yet the product – hence, the product will have a higher free energy. While the statement is true, the given reasons for it being true are incorrect.

Dinate system, and a charge q = - 2.00 nc is placed s2 10 n> c. (a) what is the change in electric potential energy when the dipole moment of a molecule changes its orientation with respect to es from parallel to perpendicular? (b) at what absolute temperature t is the average translational kinetic energy 32 kt of a molecule equal to the change in potential energy calculated in part(: abovethistemperature,thermalagitationprevents the dipoles from aligning with the electric field.) placed in a uniform electric field e with magnitude 1.6 * 6 on the positive x-axis at x = 4.00 cm. (a) if a third charge q3 = +6.00 nc is now placed at the point x = 4.00 cm, y = 3.00 cm, find the x- and y-components of the total force exerted on this charge by the other two. (b) find the magnitude and direction of figure p21.62 ll uu 21.55 . torque on a dipole. an electric dipole with dipole moment ps is in a uniform external electric field es. (a) find the orientations of the dipole for which the torque on the dipole is zero. (b) which of the orientations in part (a) is stable, and which is unstable? (hint: consider a small rotation away from the equi- librium position and see what happens.) (c) show that for the stable orientation in part (b), the dipole’s own electric field tends to oppose the external field. 21.62 ..

Two point charges are separated by a certain distance. how does the strength of the electric field produced by the first charge, at the position of the second charge, change if the second charge is doubled? a. the field does not change b. the field strength decreases by half. c. the field strength doubles d. the field strength quadruples
