Boyle's law of ideal gas: This law states that the volume of a gas is inversely proportional to its pressure at a constant temperature. Acc to this law we can write the relation of pressure and volume as:
That means:
From that equation we can calculate Volume of gas at a certain pressure:
P₁=Initial pressure
V₁=Initial volume
P₂=Final pressure
V₂= Final volume
Here P₁, initial pressure is given as 85.0 kPa
V₁, initial volume is given as 525 mL
P₂, final pressure is 65.0 kPa
so,
V_{2}=85\times 525\div 65
=686 mL
Volume of gas will be 686 mL.
Answer:
Rate =
Explanation:
- Two reactants are present in this reaction which are
- We know overall order of a reaction is summation of individual order with respect to reactants present in rate law equation.
- Here, overall order of reaction is 2 including first order with respect to
- So, rate of reaction should also be first order with respect to another reactant i.e. first order with respect to
- So, rate law: rate =
Answer:
is the approximate energy of one photon of this light.
Explanation:
Energy of the photon can be calculated by
(Planck's equation)
where,
E = energy of photon
h = Planck's constant =
c = speed of light =
= wavelength of light =
= frequency of the light
we have ,
Now put all the given values in the above formula, we get the energy of the photons.
is the approximate energy of one photon of this light.
