Question

Many exergonic reactions fail to happen at a reasonable rate (e.g. conversion of diamonds to charcoal). This is due to the fact that their activation energy may be too high to overcome. Which of the following correctly describes the reason for this
O The free energy of the transition state is much lower than the free energy of the reactants
O The free energy of the transition state is much higher than the free energy of the reactants.
Many exergonic reactions fail to happen at a reasonable rate (e.g. conversion of diamonds to charcoal). This is due to the The enzyme that catalyzes the reaction needs time to interact chemically with the substrate(s).
The interaction between the enzyme and substrate(s) involve a decrease in entropy, which can't happen input of energy

Answer 1

Answer:

The correct answer is "The free energy of the transition state is much higher than the free energy of the reactants".

Explanation:

Activation vitality is the base measure of vitality required to begin a concoction response. The wellspring of this initiation vitality is generally the warmth from the encompassing. An Enzyme builds the pace of a compound response by bringing down its actuation vitality.  

During a compound response, new bonds are made and old ones are broken. Since the bonds are vitality putting away , this prompts arrival of vitality when broken, However, To get the particles into a state where their bonds can be broken, the atom ought to be mad. To accomplish this shape, Activation vitality is required, which is a high-vitality flimsy state.  

Because of the above explanation, cells at time couple exergonic reaction(\DeltaG<0) with endergonic reaction(\DeltaG>0), permitting them to continue. This is known as vitality coupling and is unconstrained. At the point when the exergonic response discharges free vitality, consumed by the endergonic response.
