What makes a reaction rate faster?
The more surface area on which collisions can occur, the faster the reaction. Usually, an increase in temperature causes an increase in the reaction rate. Catalysts lower the activation energy of a chemical reaction and increase the rate of a chemical reaction without being consumed in the process.
How do you calculate rate?
Use the formula r = d/t. Your rate is 24 miles divided by 2 hours, so: r = 24 miles ÷ 2 hours = 12 miles per hour. Now let’s say you rode your bike at a rate of 10 miles per hour for 4 hours.
What are two ways to measure the rate of reaction?
If a reaction produces a gas such as oxygen or carbon dioxide, there are two ways to measure the reaction rate: using a gas syringe to measure the gas produced, or calculating the reduction in the mass of the reaction solution.
What is the fast reaction?
The fast reaction is defined as the reaction which takes a shorter time to complete. The fast reaction possesses a high rate of reaction. They possess smaller activation energy. The example of fast reactions are striking a match, burning of petrol in the car engine and so forth.
How do you calculate speed in mph?
Speed = Distance / Time If distance was measured in miles and time in hours, then output will be in miles per hour (mph, mi/h), and so on for km/h, m/s, etc.
What factors speed up a reaction?
There are several factors that affect the speed of a reaction: Nature of the reactants. Particle size of the reactants. Concentration of the reactants. Pressure of gaseous reactants.
What factors make reaction go faster?
To make a reaction go faster you can heat up the liquid or make the liquid more concentrated. The rate of reaction can be measured by repeating it three times as well as adding more water. Key Factors:- Factors that will affect the reaction are the heat and the amount of water.
How to increase the speed of a reaction?
How to Improve Reaction Speed Method 1 of 3: Improving Your Physical Reaction Time. Test your reaction speed by having a friend drop a card. Method 2 of 3: Increasing Your Mental Speed. Practice making quick decisions. Method 3 of 3: Taking Care of Your Body. To stay mentally and physically quick, you must take care of yourself.
What is a measure of how fast a reaction occurs?
A fast chemical reaction is one that occurs essentially instantaneously. Often times a fast reaction is used to measure the rate of a slow reaction. A way of understanding this is to imagine a slow reaction that you can’t time because it is colorless before and after the reaction.
