What would cause the equilibrium to shift left in this reaction? CO + 3H2 ? CH4 + H2O A. Adding heat to the product mixture B. A
2 answers:
Answer:
Option A.
Explanation:
To decrease pressure by increasing volume, the equilibrium of the reaction shift to the left as the reactant side has greater number of moles than the product side.
Equilibrium also shifts to the left if temperature decreases.
Given equation is
In this case, equilibrium shifts to the left on <u>adding heat to the product mixture</u> .

Answer: Option D is correct.
Explanation: Equation given by de Broglie is:
where, = wavelength of the particle
h = Planck's constant
m = mass of the particle
v = velocity of the particle
In option A, football will have some mass and is moving with a velocity of 25 m/s, hence it will have some wavelength.
In Option B, unladen swallow also have some mass and is moving with a velocity of 38 km/hr, hence it will also have some wavelength.
In Option C, a person has some mass and is running with a velocity of 7 m/hr, hence it will also have some wavelength.
As, the momentum of these particles are large, therefore the wavelength will be of small magnitude and hence, is not observable.
From the above, it is clearly visible that all the options are having some wavelength, so option D is correct.
