A reaction has activation energy of 85kjper mol. What is the effect on the rate of raising the temperature from 20degree to 30 d
DENIUS [597]

Answer: The rate increases 3 times on raising the temperature from 20degree to 30 degree​

Explanation:

According to Arrhenius equation with change in temperature, the formula is as follows.

ln \frac{k_{2}}{k_{1}} = \frac{-E_{a}}{R}[\frac{1}{T_{2}} - \frac{1}{T_{1}}]

where k_2 = rate constant at temp T_2

k_1 = rate constant at temp T_1

E_a= activation energy

R= gas constant

T_1= temperature = 20^0C=(20+273)K=293K

T_2= temperature = 30^0C=(30+273)K=303K

ln \frac{k_{2}}{k_{1}} = \frac{-85\times 1000J/mol}{8.314J/Kmol}[\frac{1}{303} - \frac{1}{293}]

ln \frac{k_{2}}{k_{1}}=1.15

\frac{k_{2}}{k_{1}}=3

Thus rate increases 3 times on raising the temperature from 20degree to 30 degree​

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.
