Explain the Effect of surface area, Concentration on Rate of Reaction. 

What is Collision Theory?

Effect of surface area:

Ever tried to light a bonfire or a camp fire. Which burns more quickly -a block of wood or a pile of wood shavings?

Small pieces of solids, especially powders, react faster than large pieces.


As we increase the surface area, the rate of reaction increases.





Collision theory:



Effect of Concentration: 
As we increase the concentration, the rate of reaction increases.

What is Intertidal zone? Define Estuary. I ntertidal zone : O ceans are divided into zones. The shallowest part of the ocean ecosystem is called the intertidal zone. The  intertidal zone  is the area where the ocean meets the land between high and low tides. Estuary : The boundary where freshwater feeds into salt water is called an estuary .

Define Pedigree and Carrier.

Image
Define Pedigree and Carrier. Pedigree: A pedigree is a chart used to trace the history of traits in a family. They are used to study   heredity patterns. Parents and offspring are shown in a pedigree.   Horizontal lines connect parents, and vertical lines connect parents to offspring. Males are represented as boxes ; f e mal e s ar e shown as circles. Individuals with a dominant trait have a shaded shape . Unshaded shapes represent recessiv e individu a ls . C arrier : A carrier is any individual who has inherited the gene for a trait, but does not show that trait  physically.

What is 'rate of reaction'? Measuring rates of reaction.

What is 'rate of reaction'?  Measuring rates of reaction. Rate of reaction: The rate of a reaction tells us how quickly a chemical reaction happens. During a reaction, we can measure how much reactant is used up in a certain time. On the other hand, we might choose to measure now much product is formed in a certain time. Measuring rates of reaction: Measure how quickly one of the reactants is being used up.
