Answer:

E_a= 7 kJ/mol

Explanation:

In this question we have to calculate the activation energy of the mechanism,we know that the mechanism of the reaction consists of pre equilibrium step with forward and reverse activation energies as  27 kJ mol−1 and 35 kJ mol−1 , respectively.

The slowest step is the rate determining step

Activation energy of the over all reaction is

E_a= E_{a2}+E_{a1}-E_{a(-1)}

E_a= 15+27-35

E_a= 7 kJ/mol

How does distance affect the strength of the force of gravity
Otrada [13]
<span>The strength of the gravitational force between two objects depends on two factors, mass and distance. the force of gravity the masses exert on each other. If one of the masses is doubled, the force of gravity between the objects is doubled. increases, the force of gravity decreases. you can look it up in Google</span>

TRIPLE POINTS!!! I NEED HELP!!! PLEASE EXPLAIN TOO!!! What is the energy of a quantum of light with a frequency of 4.31 x 1014 1
Lelechka [254]

Answer:

The answer is

2.86 \times  {10}^{ - 19}  \: J

Explanation:

The energy of a quantum of light can be found by using the formula

<h3>E = hf</h3>

where

E is the energy

f is the frequency

h is the Planck's constant which is

6.626 × 10-³⁴ Js

From the question

f = 4.31 × 10¹⁴ Hz

We have

E = 4.31 × 10¹⁴ × 6.626 × 10-³⁴

We have the final answer as

2.86 \times  {10}^{ - 19}  \: J

Hope this helps you
