Chemistry??

Question

1. Name 4 thing that can spped up a chemical reaction? And please explain why they increase the rate of reaction ?

2.What is a chemical reaction(what takes place in a chemical reaction?)

3. The substances formed a chemical reaction are____
a. Symbols
b. products
c. yield

Answer 1

3.b

Answer 2

1. concentration of reactants (because more frequency of molecular collisions if more), temperature of reaction (more collision frequency and more energy if more), surface area of reactants (more collision frequency if less), and the catalysts used (provides alternative reaction path, and is only method to lower activation energy).

2. Reactant substances basically form product substances reaching equilibrium, and heat is either emitted or absorbed by the reaction.

3. What is formed are the products of the reaction.

Answer 3

1. (Look up why)
Heat
Surface Area (More surface area = quicker reaction)
Concentration of the reactants
Pressure of the reactants.

2.The event resulting from the mixing of different substances.

3. b. Products.

Answer 4

#3 is B products

Answer 5
