The basic premise of the collision theory is that particles must first if a reaction is to occur. Additionally, that
must be effective. To be effective, the particles must
with the and the proper amount of .
2. is the study of reaction rates which is the rate at which the disappear and the products .
3. There are five factors affecting the reaction rate:
a. of the
b. of the
c.
d.
e.
4. Use the collision theory to explain:
a. A mixture of hydrogen gas and chlorine gas reacts faster when the volume they occupy is decreased: ​ ​
b. Iron filings rust faster than iron wire: ​ ​
c. An increase in temperature increases the reaction rate:


5. Why do you think that industrial chemists are concerned with reaction rates?


6. act as catalysts in our bodies. Outside the body, sugar burns only when temperatures are above 600 ºC, but inside the body sugar burns (is oxidized) at normal body temperature, which is 37 ºC. How is this possible?
​
​
7. Double arrows in an equation mean that the equation is .
Brackets around a formula represent .
8. In a state of chemical equilibrium, the forward and reverse reactions are proceeding at the same .
9. Principle states that when a stress is applied to a system in , the system reacts to the stress.
10. Using the reaction below, predict the direction of the equilibrium displacement (left or right) when the following stresses are applied:
2 SO2 (g) + O2 (g) 2 SO3 (g) + 45 kJ
a. increasing temperature
b. decreasing pressure ​
c. adding SO2(g) ​ ​
d. removing O2(g) ​ ​
Will the [SO3] increase or decrease in the above situations?
​a. ​ ​b. ​
​c. ​ ​d. ​

mechanics (greek   is that area of science concerned with the behaviour of physical bodies when subjected to forces or displacements, and the subsequent effects of the bodies on their environment. the scientific discipline has its origins in ancient greece with the writings of aristotle and archimedes[1][2][3] (see history of classical mechanics and timeline of classical mechanics). during the early modern period, scientists such as galileo, kepler, and newton laid the foundation for what is now known as classical mechanics. it is a branch of classical physics that deals with particles that are either at rest or are moving with velocities significantly less than the speed of light. it can also be defined as a branch of science which deals with the motion of and forces on objects. the field is yet less widely understood in terms of quantum theory.

explanation:

the electron configuration that you gave me has 16 electrons ergo it has 16 protons ergo it is the element sulfur.

definition

                    entropy is a measure of the randomness or the extent of disorder of a chemical process.

                      enthalpy is a measure of the heat change of a reaction occurring at a constant pressure.

measurement units:

                        entropy is measured in joule per kelvin (jk⁻¹)   whereas enthalpy is measured in joule per mole (jmol⁻¹)

requirements:

                            entropy has no requirements or limits, and its change is measured by the division between the heat change of the chemical process and the temperature.

                              in contrast, enthalpy can only be related to the heat change of the reaction under standard conditions.
