Disappearance of NO in ...- Help!!!? The following data were collected for the rate of disappearance of NO in the reaction 2 NO(

g) + O2(g) ¨ 2 NO2(g).
Run: [NO](M) [O2](M) Initail Rate (M/s) 1 .0126 .0125 1.41 X 10^-2 2 .0252 .0125 5.64 X 10^-2 3 .0252 .0250 1.13 X 10^-1 (a) What is the rate law for the reaction? (b) What are the units of the rate constant? (c) What is the average value of the rate constant calculated from the three data sets?
(d) What is the rate of disappearance of NO when [NO] = 0.0750 M and [O2] = 0.0100 M?
(e) What is the rate of disappearance of O2 at the concentrations given in part (d)?

What kind of charge does a neutron have?
Nat2105 [25]
Neutrons actually don't carry an electrical charge, which is why they are called neutrons because they are "Neutral".

The rate of disappearance of HBr in the gas phase reaction2HBr(g) → H2(g) + Br2(g)is 0.301 M s-1 at 150°C. The rate of appearanc
jok3333 [9.3K]

Answer: 0.151

Explanation:

Rate law says that rate of a reaction is directly proportional to the concentration of the reactants each raised to a stoichiometric coefficient determined experimentally called as order.

2HBr(g)\rightarrow H_2(g)+Br_2(g

The rate in terms of reactants is given as negative as the concentration of reactants is decreasing with time whereas the rate in terms of products is given as positive as the concentration of products is increasing with time.

Rate=-\frac{1d[HBr]}{2dt}=+\frac{1d[H_2]}{2dt}=+\frac{1d[Br_2]}{dt}

Given: -\frac{d[HBr]}{dt}]=0.301

Putting in the values we get:

\frac{0.301}{2}=+\frac{1d[Br_2]}{dt}

+\frac{1d[Br_2]}{dt}=0.151

Thus the rate of appearance of Br_2 is 0.151

Which three statements about gravity and the formation of the solar system
Delicious77 [7]

Answer:

B. Gravity held the pieces of forming planets together.

c. Gravity pulled most of the matter into the center of the solar system

D. Gravity caused the planets and Sun to have spherical shapes.

Explanation:

When a collection of grains pulled together by their gravitational forces would keep in by the gravity of a star, it would eventually became bigger to the point a planet was formed.

The sun's strong gravitational force pulled most of the matter around it to the center of the solar system.

The spherical shape of planets is a result of their gravity pulling equally from all sides, shaping it into a sphere.

Reaction coordinates represent: A. The balanced equation for a chemical reaction. B. The change in pH for a chemical reaction. C
Hunter-Best [27]

Answer:

C. The potential energy change for a chemical reaction.

Explanation:

The reaction coordinate q illustrates, graphically, the energy changes during exothermic and endothermic reactions. This graphical representation of the energy changes in the course of a chemical reaction is known as reaction coordinates. A reaction coordinate is a graphical sequence of steps by which the reaction progresses from reactants through activated complexes to products. Reaction coordinates explain how far a reaction has proceeded towards the products or from the reactants.

From the images attached below, we can see the reaction coordinates in the reaction profiles.
