A slightly bruised apple will rot extensively in about 2.5 days at room temperature (25.0°C). If it is kept in the refrigerator

at 0.5°C, the same extent of rotting takes about 17 days. What is the activation energy for the rotting reaction?

Answer:

Activation energy for the rotting reaction is 4.805 x 10⁻⁶ kJ/mol

Explanation:

Use the Arrhenius equation applied for two temperatures:

Ea = R· ln(k2/k1) · (1/T1 – 1/T2)

Where

R= 8.314x10-3kJ/(mol.K)

k2/k1 = 2.5/17 = 0.147    ∴    ln(k2/k1) = - 1.92

(1/T1 – 1/T2) = 1/298K – 1/273.5K = - 0.000301 K-1

Ea = 8.314x10⁻³ x (- 1.92) x (- 0.000301 K-1)

      = 4.805 x 10⁻⁶ kJ/mol

one car accelerates at half the rate of another how much longer does it take the first car to travel a quarter mile
Orlov [11]

Answer:

t=1/4v1

Explanation:

Given data

Car one

Speed =v1

Time =t

Distance =1/4 mile

Given data

Car two

Speed =v1/2

Time =t

Distance =d

Speed =distance/time

v1=1/4/t

v1t=1/4

t=1/4*1/v1

t=1/4v1 seconds

A 6.00-μf parallel-plate capacitor has charges of 40.0 μc on its plates. how much potential energy is stored in this capacitor?
dedylja [7]

Thew energy stored in a capacitor of capacitance C and voltage between the plates V is

E=\frac{1}{2} CV^2=\frac{1}{2C} Q^2.

Substituting numerical value

E=\frac{1}{2*6*10^{-6}} (40*10^{-6})^2\\ E=133.33\; \mu J

What statement is true about earth tectonic plates
DaniilM [7]
Continent jig-saw shapes when puzzled and combined together, formed one big continent - Pangea, and was separated by drifts.

Fossil comparisons of different species were discovered into two different, separated continents in which when you combine them, they were one in the past.

Seismic, volcanic, and geothermal activity are found along imagined plate boundaries. 

Plates were actually rubbing against each other as evidence is seen on the formed mountain ranges.

Light is emitted by electrons when they drop from one energy level to a lower level. Which transition results in the emission of
natulia [17]

Answer:

Level 4 to level 2

Explanation:

Electrons in an atom are contained in specific energy levels (1, 2, 3, and so on) having different distances from the nucleus. When light is emitted by electrons from one energy level to a lower level, level 4 to level 2 has the greatest energy.

Hence, the correct option is "Level 4 to level 2".
