What is one of the slowest reactions?
The rusting of iron.
1 of 6
What is an example of a moderate speed reaction?
A metal (e.g, magnesium) reacting with acid to produce a gentle stream of bubbles.
2 of 6
What is a really fast reaction called?
An explosion, where it's all over in a fraction of a second.
3 of 6
What does the rate of a reaction depend on? (4 things)
Temperature, Concentration (or pressure for gases), Catalyst and Surface Area of a solid (or size of particles).
4 of 6
What is the quickest reaction shown by in a graph? Compare to the slowest.
The line that becomes flat in the least time. The quickest reaction will also start with the steepest slope, and the slowest reaction with the shallowest slope.
5 of 6
Why could there be an increased rate?
1-Increase in temperature. 2- Increase in concentration (or pressure) 3- Catalyst added. 4- An increase in surface area (e.g, a solid reactant crushed up into smaller bits).
