You will be adding a solution containing potassium carbonate to a solution containing hydrochloric acid. What risk is associated

with this?
Chemistry
1 answer:
Phantasy [73]3 years ago
7 0

Explanation:

The reaction of potassium carbonate with hydrochloric acid is as follow -

Potassium Carbonate + Hydrochloric acid → Potassium Chloride + Water + Carbon Dioxide.

In the above reaction , the metal carbonate reacts with an acid to give salt , water and carbon dioxide .

The reaction is an exothermic reaction , as the release of carbon dioxide , is indicated by vigorous effervescence .

Hence ,

The temperature of the reaction increases a lot and hence the reaction is very dangerous .

Therefore , the reaction is very risky to perform.

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​
