Inhibitor
Explanation:
Adding an inhibitor will slow down a chemical reaction. Inhibitors works like a negative catalyst.
The addition of a foreign body can influence the rate of a reaction.
- When a foreign body slows down a reaction, it is called an inhibitor.
- An inhibitor is a negative catalyst that will slow down a reaction.
- Such substances do not allow a reaction to proceed freely and very fast.
- They work in the opposite way a normal catalyst would.
- It is good to know conditions and chemicals that can inhibit a chemical reaction.

Speed is the time rate at which Sue covers the distance. It is derived by dividing the total distance covered by the total time taken to cover the distance . Usually SI unit for speed is km/h or mph or m/s.
Explanation:
Speed is also referred to as velocity- so the two are synonymous.
Acceleration is the rate at which speed is increasing. It is usually given by SI unit m/s². The opposite of acceleration is deceleration which is the rate at which speed is decreasing.
Distance is the measurement, in meters of kilometers or miles or yards..etc, that has been covered from one point to another.
