Chapter 14 Organic chemistry

K

________ is the rate constant- a constant for each chemical reaction at a given temperature.

Arrhenius equation

The ________ is most commonly used to calculate the activation energy of a reaction.

decomposition of hydrogen peroxide

The ________ is a slow, one- step reaction, especially if the solution is kept cool and in a dark bottle:

T

________ is the Kelvin temperature, and Ea is the activation energy, the minimum amount of energy that is needed to initiate or start a chemical reaction.

Carbon

________ has the ability to bond to itself in long and complex chains.

Homogeneous catalysts

________ are catalysts that are in the same phase or state of matter as the reactants.

heterogeneous catalyst

A(n) ________ is in a different phase or state of matter from the reactants.

alternative reaction pathway

They provide a(n) ________ (a mechanism) with lower activation energy.

catalyst

Most commonly, the ________ is a solid and the reactants are liquids or gases.

Alkanes

________ are hydrocarbons that contain only single covalent bonds within their molecules.

Arrhenius equation

The ________ has the form: k= Ae- Ea /RT where k is the rate constant, A is a term called the frequency factor that accounts for molecular orientation, e is the natural logarithm base, R is the universal gas constant 8.314 J mol K- 1, T is the Kelvin temperature, and Ea is the activation energy,
