Answer:
D) speed
Explanation:
Reaction rates can be affected by several factors, including concentration, temperature, surface area and presence of a catalyst. Increasing concentration increases the number of effective collisions. Increasing temperature increases the kinetic energy of the particles, leading to more effective collisions
Answer:
Explanation:
They are the gases that conform to gas laws under all conditions of temperature and pressure. They are the gases that conform precisely to the assumptions of kinetic theory. ideal gases according to the kinetic theory assumptions could have no significant volume and there is no attractive or repulsive forces between its particles. there is no gas for which these assumptions are true; an ideal gas does not exist. However, under many coditions of temperature and pressure real gases behave much like ideal gases. Real gases have volume and there are attractions between their particles. Because of these attractions, real gases can be solidified or condensed when compressed or cooled e.g. water vapor when cooled below 100 degrees celsius at standard atmospheric pressure can be condensed into liquid. other real gases behave like that but sometimes more pressure and less temperature is required.
Assumptions of kinetic theory:
- the volume of a single particle in gas is small compared to the overall volume of the gas.
- under pressure, the particles are compressed and come closer together.
- there are no attractice or repulsive forces between its particles so it can move freely
- it expand to take the shape and size of the container
- the particles of the gas move in straight path until they collide with the wall of the container or with each other
- the motion of the particles is rapid, random and constant
- the distance between the particles of gas is more than that between solids and liquids
Answer:
Explanation:
The last number in a measured number is always an estimated digit.
The partial pressure of gas C is 0.54atm. The correct option is D.
<h3>What is partial pressure?</h3>
The pressure that one of the gases in a mixture would exert if it were in the same volume on its own.
The total pressure of A, B and C is 6.11 atm.
The partial pressure of A is 1.68 atm
The partial pressure of B is 3.89 atm.
Total pressure = sum of partial pressures of all the gasses in that mixture
6.11atm = 1.68atm + 3.89atm + Pc
Pc = 6.11atm - (1.68 + 3.89) = 0.54atm
Thus, the partial pressure of C is 0.54atm. The correct option is D.

Answer:
False
Explanation:
The octet rule forms the basis for chemical reactions. The octet rule states that; an atom is only stable when it has eight electrons around its outermost shell.
This implies that the driving force behind chemical reaction is the attainment of an octet structure(eight electrons in the outermost shell of each of the bonding atoms).
An atom that has only six electrons in its outermost shell is not yet stable according to the demand of the octet rule. Hence, the statement "chemical reactions happen and compounds form because they're trying to get 6 electrons in their outer orbitals" is false.
