A bottle contains 2.5 moles of KOH dissolved in water, and the molarity of the solution is 0.16 M.

alexdok [17]

Answer:

V = 15.6 L

Explanation:

Hello there!

In this case, according to the definition of molarity in terms of the moles of solute divided by the volume of the solution, it is possible for us to write:

$M=n/V$

Thus, given the moles and concentration of the solution, we can find the volume as shown below:

V=n/M

Therefore, we plug in the given data to obtain:

V = 2.5mol /(0.16mol/L)

V = 15.6 L

Best regards!

A sample of milk kept at 25 °C is found to sour 40 times as rapidly as when it is kept at 4 °C. Estimate the activation energy f

irga5000 [103]

Answer:

120.575 kJ is the activation energy for the souring process.

Explanation:

The formula for an activation energy is given as:

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

where,

$K_1$ = rate constant at $25^oC$ = $40k$

$K_2$ = rate constant at $4^oC$ = $k$

$Ea$ = activation energy for the reaction = ?

R = gas constant = 8.314 J/mole.K

$T_1$ = initial temperature = $25^oC=273+25=298 K$

$T_2$ = final temperature = $4^oC=273+4=277 K$

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

$\log (\frac{k}{40k})=\frac{Ea}{2.303\times 8.314 J/mol K}[\frac{1}{298K}-\frac{1}{277 K}]$

$E_a=120,575.61J=120.575 kJ$

120.575 kJ is the activation energy for the souring process.

Which law states that the entropy of the universe is always increasing?

vova2212 [387]

Second law of thermodynamics states entropy of the universe is always increasing. entropy always increases in a spontaneous process .

option B) second law of thermodynamics

for example if we keep a hot cup of coffee the heat is lost to surrounding and entropy( randomness increases) since it is a natural process entropy of universe increases.
