For the following reaction, the equilibrium constant Kc is 2.0 at a certain temperature. The reaction is endothermic. What do yo
jeyben [28]

Answer:

The correct answer is : 'the concatenation of NO will increase'.

Explanation:

Any change in the equilibrium is studied on the basis of Le-Chatelier's principle.

This principle states that if there is any change in the variables of the reaction, the equilibrium will shift in the direction to minimize the effect.

If the temperature is increased, so according to the Le-Chatlier's principle , the equilibrium will shift in the direction where increase in temperature occurs.

2NOBr(g)\rightleftharpoons 2NO(g) + Br_2(g)

As, this is an endothermic reaction, increasing temperature will add more heat to the system which move equilibrium in the forward reaction with decrease in temperature. Hence, the equilibrium will shift in the right direction.

So, the concatenation of NO will increase.

WORTH 80 POINTS PLEASE HELP
Verdich [7]

The two bulges are called tidal bulges. There are two tidal bulges on opposite sides of Earth. One is beneath the moon and the other is opposite to that. The one below the moon is thought of as gravitational. It is produced by gravitational attraction between water molecules in the ocean and the moon.

<span>Now, about the other bulge. Think about inertia and what happens when masses rotate around a single point. Imagine yourself swinging a bucket of any liquid with your arm in a circular gesture. Even as the bucket goes over your head, the water is still held in the bucket and doesn't splash all over you. This rotation creates a centrifugal force. A similar event occurs during the lunar month as the earth/moon system rotates. The moon orbits the earth, but the rotation axis for this orbit isn't earth's center. Both the moon and Earth move during the roughly 28-day period it takes for the orbit, and because of this, water in the ocean is thrown to the outside, the same as the water in your bucket. The tidal bulge on the opposite side of Earth from the moon is produced by this inertial effect, referred to as centrifugal force.</span>

Aniline involves an amine, which is a Choose... functional group. When an aqueous acid solution is added to an organic solution
Charra [1.4K]

Answer:

Basic

Aqueous

Protonated

Reconstitute

Explanation:

Aniline contains the -NH2 group in which the hydrogen atom bears a lone pair of electrons which is capable of accepting a proton hence aniline is basic.

This lone pair makes it possible for aniline to be protonated to yield an ionic substance which enters into the aqueous phase.

Addition of a base leads to the reconstitution of the aniline.

Assume that the rate law for a generic chemical reaction is rate = [a][b]3 . what is the reaction order in a, the reaction order
SIZIF [17.4K]
If the reaction is
     X + Y → Products

Then the rate is
     R = k[X]ᵃ [Y]ᵇ

Where,
R = the rate of the reaction (mol L⁻¹ s⁻¹)
k = rate constant
[X] and [Y] = concentrations of the reactants (mol L⁻¹)
a = order of the reaction with respect to X
b = order of the reaction with respect to Y
overall reaction order, n = a + b

according to the given rate expression,
rate = [a][b]³

order of the reaction with respect to 'a' is 1
order of the reaction with respect to 'b' is 3

Overall reaction order = 1 + 3
                                       = 4
