A student performs a reaction twice. In the second trial, he increases the temperature of the reaction and notes that the reacti

on happens more quickly. The student concludes that this means the reaction was endothermic. What is wrong with the student's reasoning?
Higher temperature increases reaction rates for both endothermic and exothermic reactions.
An endothermic reaction would not speed up at higher temperatures.
Temperature does not affect the rate of a reaction.
The higher temperature in the second trial actually lowered the activation energy of the reaction.

Answer:

n=6.56×10¹⁵Hz

Explanation:

Given Data

Mass=9.1×10⁻³¹ kg

Radius distance=5.3×10⁻¹¹m

Electric Force=8.2×10⁻⁸N

To find

Revolutions per second

Solution

Let F be the force of attraction

let n  be the number of revolutions per sec made by the electron around the nucleus then the centripetal force is given by

F=mω²r......................where ω=2π  n

F=m4π²n²r...............eq(i)

as the values given where

Mass=9.1×10⁻³¹ kg

Radius distance=5.3×10⁻¹¹m

Electric Force=8.2×10⁻⁸N

we have to find n from eq(i)

n²=F/(m4π²r)

n^{2} =\frac{8.2*10^{-8} }{9.11*10^{-31}* 4\pi^{2} *5.3*10^{-11}  }\\ n^{2}=4.31*10^{31}\\ n=\sqrt{4.31*10^{31}}\\ n=6.56*10^{15}Hz
