An exothermic reaction is a chemical reaction that releases heat. it does not absorb
Change of matter
- Know simple science rules and that will help.
An unsaturated hydrocarbon with a double bond is called an alkene. hope i helped.
:)
The
for the process is 7265.2 Joules/mol.
<h3>Calculation of

:</h3>
Instead of providing us with the rate constants at two distinct temperatures, the information in the issue provides us with the time needed at two different temperatures.
For a specific process, the ratio of rate constants will match the ratio of rates.
A ratio of rates will have an inverse relationship with a ratio of times since rates are inversely related to time (greater time equals smaller rate). Below is a summary of this.
Using Arrhenius equation:
ln![\frac{k_{1} }{k_{2} } =\frac{-Ea [1/T_{2} -1/T_{1}] }{R}](https://tex.z-dn.net/?f=%5Cfrac%7Bk_%7B1%7D%20%7D%7Bk_%7B2%7D%20%7D%20%3D%5Cfrac%7B-Ea%20%5B1%2FT_%7B2%7D%20-1%2FT_%7B1%7D%5D%20%7D%7BR%7D)


= 273 +100
= 373 K
= 273 + 90
= 363 K
Gas constant R = 8.314 Joules/Kelvin.mol
ln4.8/4.5 = -Ea/8.314 [1/373 - 1/363]
0.064539 x 8.314 = Ea x 0.000073856
= 7265.2 Joules/mol
Hence, The
for the process is 7265.2 Joules/mol.
