The activation energy for a given reaction is 56 kj/mol. at what temperature would the rate constant be quadruple what is was at
Alex787 [66]

The rate equation is given as:

k = A e^(- Ea / RT)

 

Dividing state 1 and state 2:

k1/k2 = e^(- Ea / RT1) / e^(- Ea / RT2)

k1/k2 = e^[- Ea / RT1 - (- Ea / RT2)]

k1/k2 = e^[- Ea / RT1 + Ea / RT2)]

 

Taking the ln of both sides:

ln (k1/k2) = - Ea / RT1 + Ea / RT2

ln (k1/k2) = - Ea / R (1/T1 - 1/T2)

 

Since k2 = 4k1, therefore k1/k2 = ¼

 

ln (1/4) = [- (56,000 J/mol) / (8.314 J / mol K)] (1/273 K – 1/ T2)

2.058 x 10^-4 = 1/273 – 1/T2

T2 = 289.25 K

Based on the electron configuration of the two atoms, predict the ratio of metal cationic (+) atom to nonmetal anionic (-) atom
Pepsi [2]

The metal cationic (+) atom to nonmetal anionic (-) atom ratio in the compound formed between Potassium and Chlorine is 1:1.

<h3>What is a compound?</h3>

A compound is made up of two or more atoms that are chemically combined together. In this case, we have the atoms; Potassium and Chlorine.

The electronic configuration of the atoms is not shown here but the metal cationic (+) atom to nonmetal anionic (-) atom ratio in the compound formed between Potassium and Chlorine is 1:1.

Calculate the pH for each of the following cases in the titration of 50.0 mL of 0.210 M HClO(aq) with 0.210 M KOH(aq).
laiz [17]
<span>35.0 mL of 0.210 M
KOH molarity = moles/volume
 find moles of OH do the same thing for: 50.0 mL of 0.210 M HClO(aq) but for H+ they will cancel out: H+ + OH- -> H2O
 but you'll have some left over,
 pH=-log[H+] pOH
     =-log[OH-] pH+pOH
     =14</span>
