a chemical property of iron is the ability to change it, hammer it, roll it, shape it etc
When the initial concentration of crystal Violet is double, the rate of the reaction will rise up about four times the initial rate.
<h3>What is the rate of chemical reaction?</h3>
The rate of a chemical reaction refer to the rate of change in concentration of the reaction over the change in time. Introduction.
When you double the concentration the rate doubles. The rate is proportional to the square of the concentration of a reactant. When the rate is doubled the concentration rate goes up four times. The rate is not affected by the concentration of a reactant.
