Kinetic Control

Definition

A situation where reaction rate, often limited by high activation energy, prevents noticeable product formation.

1 / 8
Kinetic Control
Not Started

A situation where reaction rate, often limited by high activation energy, prevents noticeable product formation.

9.4.A9.4.A.2
Thermodynamic Favorability and Reaction Rate
Not Started

A negative ΔG means a process is favorable, but it may still occur extremely slowly.

9.4.A9.4.A.1
Thermodynamic Control
Not Started

Reaction behavior determined mainly by the free-energy difference between reactants and products.

9.4.A
Thermodynamically Favored but Not at Equilibrium
Not Started

A system may have a favorable forward process yet remain far from equilibrium if rate is negligible.

9.4.A9.4.A.2
Catalyst and Kinetic Control
Not Started

A catalyst provides a lower-energy pathway, increasing rate without changing overall thermodynamic favorability.

9.4.A9.4.A.2
Diamond to Graphite Conversion
Not Started

A spontaneous carbon allotrope change with negative ΔG that occurs extremely slowly because of a large barrier.

9.4.A9.4.A.2
Hydrogen Peroxide Decomposition with Iodide Catalyst
Not Started

A usually slow favorable reaction that becomes measurable when iodide lowers the activation energy.

9.4.A9.4.A.2
Activation Energy and Kinetic Control
Not Started

A large activation-energy barrier can keep a thermodynamically favored reaction extremely slow.
