Answer : The value of rate of reaction is 
Explanation :
Rate law : It is defined as the expression which expresses the rate of the reaction in terms of molar concentration of the reactants with each term raised to the power their stoichiometric coefficient of that reactant in the balanced chemical equation.
The given chemical equation is:
Rate law expression for the reaction is:
![\text{Rate}=k[NO]^a[O_2]^b](https://tex.z-dn.net/?f=%5Ctext%7BRate%7D%3Dk%5BNO%5D%5Ea%5BO_2%5D%5Eb)
As per question,
a = order with respect to 
= 2
b = order with respect to 
= 1
Thus, the rate law becomes:
![\text{Rate}=k[NO]^2[O_2]^1](https://tex.z-dn.net/?f=%5Ctext%7BRate%7D%3Dk%5BNO%5D%5E2%5BO_2%5D%5E1)
Now, calculating the value of rate of reaction by using the rate law expression.
Given :
k = rate constant = 
[NO] = concentration of NO = 
![[O_2]](https://tex.z-dn.net/?f=%5BO_2%5D)
= concentration of = 
Now put all the given values in the above expression, we get:
Hence, the value of rate of reaction is
Since the molecule contains Hydrogen and is covalently bonded, it contains dipole-dipole forces and hydrogen bonds.

When something is cooling it isn’t changing it’s chemical composition so it’s physical
Answer:
Connecting wires provide a medium to an electrical current so that they can travel from one point on a circuit to another. ... In a basic circuit, the wire comes from one terminal of a power source, then connects to a switch that determines whether the circuit is open or closed.
Explanation:
This can be solve using the grahams law, which states that the rate of diffusion of the gas is inversely proportional the square root of the molar mass of the gas. meaning the gas with smaller molar mass is the fastest to diffuse
molar mass of the following
F2 = 38 g/mol
CO2 = 44 g/mol
He = 4 g/mol
SO2 = 64 g/mol
NO = 30 g/mol
NH3 = 17 g/mol
so the fastest is He
