A zero-order reaction has a constant rate of 4.40×10−4 m/s. if after 45.0 seconds the concentration has dropped to 1.50×10−2 m, what was the initial concentration? express your answer with the appropriate units.

Respuesta :

We have that the initial concentration  is mathematically given as

1 * {10}^{-11} M

Concentration

Generally the equation for the PH  is mathematically given as

[tex]pH = - log [ {H}^{+} ]\\\\given the H+ ions we discover the antilog of the pH\\\\11 = - log({H}^{+}) \\\\{H}^{+} = {10}^{ - 11}\\\\[/tex]

Therefore

1 * {10}^{-11} M
