In GCSE chemistry, students will look at the different rates of chemical reactions. This is the first of three GCSE Chemistry quizzes looking at these factors. The rate of a reaction is a measure of how quickly a chemical reaction progresses.
Rate of reaction/Speed of reaction: It is the speed for a reactant to be used up or product to be formed. The rate of reaction increases during the first few seconds because a. the amount of magnesium is decreasing b. the magnesium is acting as a catalyst c. the...

Likewise, the rate of a chemical reaction is a measure of how much reactant is consumed, or how much product Reaction rates are therefore determined by measuring the time dependence of some property that can be related to reactant or product amounts.
Definition of reaction rate, and examples of calculating the average rate of reaction. Google Classroom. - 0.02 here, over 2, and that would give us a negative rate of reaction, but in chemistry, the rate of reaction is defined as a positive quantity.

The Reaction Rate for a given chemical reaction … The reaction rate can be determined by measuring how fast the concentration of A or B decreases, or by how fast the concentration of AB Notice the minus signs in the first two examples above.
The rate of a reaction is a powerful diagnostic tool. By finding out how fast products are made For example, a slow rate of reaction might indicate that not many of the collisions are For example an exothermic reaction might produce heat and we can monitor the...
Reaction rate The speed of a chemical reaction may be defined as the change in concentration of a substance divided by the time interval during which this change is observed: rate=Δconcentration/Δtime There are numerous types of reactions, having ...
