Answer:
C
Explanation:
Temperature is directly related to kinetic energy (KE). As we raise temperature, we are raising KE, as well. Particles with more KE move more quickly and with more force.
This means that these particles are more likely to collide with each other and react to allow the chemical reaction to follow through. In turn, if the chemical reaction is more likely to go to completion, the reaction rate increases, eliminating A and B.
The concentration of the solute is not affected by the temperature; in other words, temperature will not increase or decrease the amount of solute in the solution, so eliminate D.
Thus the answer is C.

<h2>A sample of gold (Au) has a mass of 72.04g. Calculate the number of atoms of gold (Au): It is equal to ==2.207 x 10²³ number of atoms </h2>
Explanation:
we can find number of atoms in a given sample by the formula :
Number of atoms = Given mass /atomic mass x Avogadro's number
or , it can be written as :
Number of atoms = given mass /atomic mass x 6.022 x 10²³
Now in above asked question , the values given are :
Mass of sample of gold = 72.04g
Atomic mass of gold : 196.6
Avogadro's number = 6.023 x 10²³
so, using the above formula we have :
Number of atoms = 72.04 /196.6 x 6.022 x 10²³
= 0.3664 x 6.022 x 10²³
=2.207 x 10²³ number of atoms
