Answer:
Hey!
Your answer is The Rate of a Reaction is a measurement of how the speed at which a reactant is used up / or a product is formed.
Step-by-step explanation:
R of R (Rate of Reaction) can be affected by:
Reactant concentration (how much of the substance is there to react)
The state of the reactants (whether they are in a solid/liquid/gas state)
The total surface area (more particles of the substance means more reactions...)
The Temperature (hot=quicker cool=slower)
The presence of a catalyst (catalysts speed up the Rate of the Reaction)
