Answer:
Gamma ray
Explanation:
Radio waves have low energy photons, microwave photons have a little more energy than the radio waves, infrared photons have more energy than the microwave, then visible, ultraviolet, X-rays, and, the most energetic of all is the gamma-rays
Answer:
5000 and indicate that there is more B than A at equilibrium
Explanation:
For the given reaction:
where [B] and [A] represents equilibrium concentration B and A respectively. K represents equilibrium constant
More B than A at equilibrium means, [B] > [A]
So,
As, both 5000 and are greater than 1 therefore these two K values indicate that there is more B than A at equilibrium
<em>Answer:</em> 20 m/min east
<em>Explanation:</em> The speed is distance divided by time
distance between start-point and end-point = 100 meters
<em>time to cover the distan</em>ce = 5 minutes
100 m ÷ 5 min = 20 m/min east
y<u>ou have to add east since velocity is the measure of speed and direction and your answer needs to include the direction</u>
Answer:
rate = k[A][B] where k = k₂K
Explanation:
Your mechanism is a slow step with a prior equilibrium:
(The arrow in Step 1 should be equilibrium arrows).
1. Write the rate equations:
2. Derive the rate law
Assume k₋₁ ≫ k₂.
Then, in effect, we have an equilibrium that is only slightly disturbed by C slowly reacting to form D.
In an equilibrium, the forward and reverse rates are equal:
k₁[A][B] = k₋₁[C]
[C] = (k₁/k₋₁)[A][B] = K[A][B] (K is the equilibrium constant)
rate = d[D]/dt = k₂[C] = k₂K[A][B] = k[A][B]
The rate law is
rate = k[A][B] where k = k₂K
