which of the following best helps explain why an increase in temperature increases the rate of a chemical reaction?
NeTakaya

The given question is incomplete. The complete question is as follows.

Which of the following best helps explain why an increase in temperature increases the rate of a chemical reaction?

(a)   at higher temperatures, high-energy collisions happen less frequently.

(b)  at low temperatures, low-energy collisions happen more frequently.

(c)   at higher temperatures, less-energy collisions happen less frequently.

(d)  at higher temperatures, high-energy collisions happen more frequently

Explanation:

When we increase the temperature of a chemical reaction then molecules of the reactant species tend to gain kinetic energy. As a result, they come into motion which leads to more number of collisions within the molecules.

Therefore, chemical reaction will take less amount of time in order to reach its end point. This means that there will occur an increase in rate of reaction.

Thus, we can conclude that the statement at higher temperatures, high-energy collisions happen more frequently, best explains why an increase in temperature increases the rate of a chemical reaction.

Can someone please help with this I need the answers for the three boxes
denis23 [38]

Answer:

Type: M

Name: Dixytrogen Pentasulfide

Molar Mass:

X*2 = Number * 2 = Number

S*5=32.066*5=160.33

Number + 160.33 = Molar Mass (g/mol).

(The mass for Xytrogen is not present).

Explanation:

Assuming Xytrogen is a non-metal and bonding it with sulfur, another non-metal would make it covalent or molecular.  

The name is from the amount of Xs (being two [Di]) and the amount of Ss (being five [Penta]).

The molar mass is explained above.  You need to multiply the mass of each element by the number of elements present in the compound.  The mass for Xytrogen is not present (as it is a made up element) so I left instructions how to do it once given the mass instruction.

Hope this helps.
