Calculate the pH of a solution if the concentration of hydronium ions (H3O+) is 4.8 x 10-11M?
Gelneren [198K]

Answer:

Explanation:

[ H₃O⁺¹] = 4.8 x 10⁻¹¹ mol / l

H₃O⁺¹ = H₂O + H⁺

[ H₃O⁺¹] = [H⁺]

pH = -log[H⁺]

= -log[ 4.8 x 10⁻¹¹]

= -log 4.8 + 11

= - 0 .68 + 11

= 10.32

A reversible reaction has a forward rate constant of 0.412 mol/L/s and a reverse reaction rate constant of 0.827 mol/L/s. What's
andrey2020 [161]

Answer: 0.498

Explanation:

Given the following :

Forward rate constant (Kf) = 0.412 mol/L/s

Reverse rate constant (Kr) = 0.827 mol/L/s

The ratio of the rate constant for the forward reaction and the rate constant for the reverse reaction produces the equilibrium constant.

Therefore,

Keq = (forward rate constant (Kf) / Reverse rate constant)

Keq = 0.412mol/L/s / 0.827mol/L/s

Keq = 0.498
