Q. No.15. The correct statemens are
If Go
<0, then equilibrium constant, K will be greater than 1 because
Go =
-RTlnK if K>1 then
Go is
negative and less than zero.
The reaction step with the highest energy transition state is the slow step and is the rate determining step.
Question 15 Identify correct statements pertaining to reaction energies. The rate of a reaction depends on...
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.
Identify correct statements pertaining to reaction energies. Group of answer choices The rate of a reaction depends on the energy change between reactants and products. If Keq < 1, the equilibrium will favor the reactants. If ∆G° < 0, Keq will be greater than 1. The reaction step with the highest energy transition state is called the rate determining step.
(a) Select all of the correct statements about reaction rates from the choices below. The lower the rate of a reaction the longer it takes to reach completion. The rate of a slow step has more effect on the overall reaction rate than the rate of a fast step. As a reaction progresses its rate goes down. Concentrations of homogeneous catalysts have no effect on reaction rates. Reaction rates always increase as masses of solid reactants increase. The fastest step...
