The Reaction Rate decreases as the reaction proceeds. Reason: the concentration of reactants decreases. •. Any substance in the reaction can be used to express ...

Measures the speed of the chemical reaction, determining how fast or slow it is. It is defined as the change in concentration of reactants or products per unit.

The rate of a chemical reaction can be found by measuring the quantity of a reactant used or the quantity of product formed over time: The quantity of reactant ...

Calculate average rates of chemical reactions from experimental data. • Relate rates of chemical reactions to collisions between reacting particles. Vocabulary.

(3) Concentration of reactants: The rate of a chemical reaction is directly proportional to the concentration of the reactants means rate of reaction decreases ...

A catalyst is a substance the ALTERS the rate of a reaction but is not consumed in the reaction. Negative catalysts or inhibitors slow down the rate, e.g. ...

▶ Initial rate: It is the rate of reaction between time zero (that is initial time when t = 0) and a given time.

The four main factors that affect the rate of chemical reactions are. • Concentration of the reactants,. • Temperature of the reactants,. • Surface area of the ...

The rate of a chemical reaction is the speed at which the reactants are used up or the speed at which new products are formed. In order to measure the rate of a ...

The variables that affect the reaction rate are essentially the concentration of the reactant(s) and the temperature. In the case of gas-phase reactions, the ...
