Question

The reaction C(s) + H_2 O(g) equivalent CO(g) + H_2 (g) is allowed to reach equilibrium in a cylinder equipped with a piston. Subsequently, the piston is pushed inwards, resulting in a decrease in the volume of the cylinder. As a result, the equilibrium: Will shift to the right Will shift to the left Will not shift Cannot tell Sulfuric acid, H_2 SO_4, is a very strong acid. The pH of an aqueous solution of 0.018 M H_2 SO_4 (OH)_2 at room temperature (25 degree C) is: 1.44 1.74 2.00 2.05 2.89 7.00 12.26 12.56 The acid dissociation constant, K_a, of glycine (0-aminoacetic acid) is 1.67 * 10^-10. The pH of solution is 0.084 M glycine in water is: 1.08 2.71

Explanation / Answer

when you half of the decrese the volume pressure of the container will increse

reaction will shift towards decrease pressere

so reaction will shift to wards reactant side

so reaction will shift left side option b is the correct answer

20

H2SO4 is strong acid = so it will dissociate 100%

it is a diprotic acid

= 2 x 0.018 M

= 0.036 M

pH = -log(H3O+)

pH = -log(0.036) = 1.44

option a is the correct answer
