WebUsing the values for rate 1 and the order of iodine from above, we can calculate k from the following equation: rate = k[acetone]m[HCl]n[I 2] p 4.2 * 10-6 = k[0.80]1[0.20]1[0.0010]0 and solving for k we get a value of k = 2.6 * 10-5 M-1 s-1 5.

Webheat of neutralization values - Example. Heat of neutralization is a measure of the amount of heat that is released or absorbed during a chemical reaction in which an acid and a base react to form a salt and water. This process is known as neutralization, as the acid and base cancel out each other's properties and produce a neutral solution.
