Answer:
<em>Recall the following terms which is,</em>
<em> KHP is Potassium hydrogen phthalate</em>
<em>NaOH is Sodium Hydroxide </em>
<em>NaKP is molar mass</em>
<em>H20 is water</em>
Explanation:
<em>KHP + NaOH = NaKP + H2O
</em>
<em>moles of KHP = 0.3480g / 204.22 g·mol−1 = .001704
</em>
<em>these will react with the same number of moles of NaOH according to the equation </em>
<em>these are in 0.03207 L of solution </em>
<em> The molarity of the NaOH solution = 0.001704 mol / 0.03207 L = 0.0531 M
</em>
<em>the water takes no part in the reaction and the quantity can be ignored
</em>

Answer:
D
Explanation:
A reaction that is exothermic and causes a decrease in the entropy of the system cannot be a spontaneous reaction. This is not totally true because naturally For a spontaneous process, the entropy of the universe (system plus surroundings) must increase. This is the 2nd law of thermodynamics. The system entropy can decrease as long as the entropy of the surroundings increases enough to make the sum of the system and surroundings positive.
And we know that a spontaneous reaction is a reaction that occurs in a given set of conditions without intervention. Spontaneous reactions are accompanied by an increase in overall entropy or disorder. If the Gibbs Free Energy is negative, then the reaction is spontaneous, and if it is positive, then it is nonspontaneous.
As the size of a star increases, luminosity increases. If you think about it, a larger star has more surface area. That increased surface area allows more light and energy to be given off. Temperature also affects a star's luminosity.
<u>The given reaction is:</u>
F2 + ClO2 → 2FClO2
Rate = k[F2][ClO2]
<u>Explanation:</u>
The possible mechanism for this reaction can be broken down into two steps with the slow step being the rate determining step
Step 1: F2 + ClO2 → FClO2 + F ----------- Slow
Step 2: F + ClO2 → FClO2 ----------- Fast
-----------------------------------------------------------
Overall: F2 + 2ClO2 → 2FClO2
Rate = k[F2][ClO2]
