Answer:

Explanation:
The Rydberg equation gives the wavelength λ for the transitions:

where
R= the Rydberg constant (1.0974 ×10⁷ m⁻¹) and

Data:

λ = 657 nm
Calculation:

Answer:

Explanation:
Hello!
In this case, since the ideal gas equation is used under the assumption of no interaction between molecules and perfectly sphere-shaped molecules but the van der Waals equation actually includes those effects, we can compute each pressure as shown below, considering the temperature in kelvins (22.3+273.15=295.45K):

Next, since the VdW equation requires the molar volume, we proceed as shown below:

Now, we use its definition:

Thus, by plugging in we obtain:

Thus, the pressure difference is:

Answer:
Enzymes are homogenous, thermolabile,biological catalyst that increases the reaction rate of a chemical reaction.
Explanation:
Enzymes are used as catalyst in many biochemical reactions.Enzymes basically interact in a complementary fashion with the transition state of the reaction thus helping to decrease the energy barrier called activation energy.Thus enzymes helps to stimulate the velocity of biochemical reaction.
It is very important point to note that enzymes do not affect the reaction equilibrium.
