The Avrami equation describes how solids transform from one phase to another at constant temperature. It can specifically describe the kinetics of crystallisation, can be applied generally to other changes of phase in materials, like chemical reaction rates, and can even be meaningful in analyses of ecological systems.

The unimolecular nucleophilic substitution (SN1) reaction is a substitution reaction in organic chemistry. The Hughes-Ingold symbol of the mechanism expresses two properties—"S N " stands for "nucleophilic substitution", and the "1" says that the rate-determining step is unimolecular. [1][2] Thus, the rate equation is often shown as having ...
e. In polymer chemistry, free-radical polymerization (FRP) is a method of polymerization by which a polymer forms by the successive addition of free-radical building blocks (repeat units). Free radicals can be formed by a number of different mechanisms, usually involving separate initiator molecules.
The CME FedWatch Tool, which measures market expectations for Fed fund rate changes, projects an 85% chance the Fed will cut rates to a range of 5.00% to 5.25%, with only a 15% chance that the Fed ...
The fixed rate for a 15-year mortgage is 5.15%, down 12 basis points from last week's average 5.27%. These figures are lower than a year ago, when rates averaged 7.19% for a 30-year term and 6.54% ...
Mortgage rates came down again ... interest rate for 30-year fixed-rate mortgages with conforming loan balances of $766,550 or less decreased to 6.15% from 6.29%, with points increasing to 0.56 ...
A typical composition of a commercial LTS catalyst has been reported as 32-33% CuO, 34-53% ZnO, 15-33% Al 2 O 3. [3] The active catalytic species is CuO. The function of ZnO is to provide structural support as well as prevent the poisoning of copper by sulfur. The Al 2 O 3 prevents dispersion and pellet shrinkage. The LTS shift reactor operates ...
5%. 4%. 3%. 2%. 1%. The interest on corporate bonds and government bonds is usually payable twice yearly. The amount of interest paid every six months is the disclosed interest rate divided by two and multiplied by the principal. The yearly compounded rate is higher than the disclosed rate.
