If a temperature increase from 18.0 ∘C to 37.0 ∘C triples the rate constant for a reaction, what is the value of the activation

iragen [17]

Answer : The activation energy for the reaction is, 43.4 KJ

Explanation :

According to the Arrhenius equation,

$K=A\times e^{\frac{-Ea}{RT}}$

or,

$\log (\frac{K_2}{K_1})=\frac{Ea}{2.303\times R}[\frac{1}{T_1}-\frac{1}{T_2}]$

where,

$K_1$ = rate constant at $18.0^oC$

$K_2$ = rate constant at $37.0^oC$ = $3K_1$

$Ea$ = activation energy for the reaction = ?

R = gas constant = 8.314 J/mole.K

$T_1$ = initial temperature = $18.0^oC=273+18.0=291K$

$T_2$ = final temperature = $37.0^oC=273+37.0=310K$

Now put all the given values in this formula, we get:

$\log (\frac{3K_1}{K_1})=\frac{Ea}{2.303\times 8.314J/mole.K}[\frac{1}{291K}-\frac{1}{310K}]$

$Ea=43374.66J/mole=43.4KJ$

Therefore, the activation energy for the reaction is, 43.4 KJ

Aleonysh [2.5K]

Mercury, Earth and Mars

Explanation:

From the given list, only Venus is not an inner planet.

Inner planets are also known as terrestrial planets. They are rocky planets with very high density. These planets are close to the sun. These planets are Mercury, Venus, Earth and Mars.

The outer planets are the gas giants. They are predominantly made up of gases. They are also called Jovian planets. They are not as dense as the Inner planets. These planets are Jupiter, Saturn, Uranus and Neptune.

Consider the reaction below. Upper N a superscript plus, plus upper C subscript 2 upper H subscript 3 upper O subscript 2 supers

Brums [2.3K]

No reaction occurs since all the ions appear on both sides of the equation, therefore, no product is formed.

<h3>What is a net ionic equation?</h3>

A net ionic equation is an equation in which the ions which appear on both sides of an ionic equation known as spectator ions are removed leaving only the products formed and the ions involved in their formation.

The equation of reaction is given below as follows:

$Na^{+} + C_{2}H_{3}O_{2}^{-} + H^{+} + Cl^{-}\rightarrow Na^{+}+ Cl^{-} +C_{2}H_{3}O_{2}^{-} + H^{+}$

The ions all appear on both sides of the equation, therefore, no product is formed.

Therefore, no reaction occurs.
