Answer:
Energy decreases and wavelength gets longer.
Explanation:
The energy of a wave is given by :
Where
h is Planck's constant
f is the frequency of the wave
As frequency decreases, the energy of the wave also decreases and wavelength gets longer. Hence, the option is (d).
Answer:
The gases will expand until a volume of Vf= 10812 cm^3
Explanation:
Since the gas mixture is expanding at constant pressure
and therefore
knowing that 1 torr=133,32 Pa
therefore
There are more reactants than the products
Explanation:
For any system in equilibrium, the molar concentration of all the species on the right hand side is related to the molar concentrations of those at the left hand side by a constant known as the equilibrium constant (K).
The constant is temperature dependent.
- When the equilibrium constant is less than 1, it implies that there are more reactants than the products.
- If the constant is equal to 1, the products and reactants are the same.
- If the constant is greater than 1, the products are more than the reactants.
