myrzilka [38]

Answer:

$t=5.84\times 10^{-5}s$

Explanation:

First rearrange the whole equation by keeping t in one side and rest parameters in another side of equation
Then plug-in all the given values for each parameters and get the solution

$ln(\frac{A}{B})=-kt$

or, $t=\frac{1}{-k}\times ln(\frac{A}{B})$

Now plug-in all given values:

$t=\frac{1}{-4.80\times 10^{4}s^{-1}}\times ln(\frac{1.00\times 10M}{1.65\times 10^{2}M})$

So, $t=5.84\times 10^{-5}s$

To determine the concentration of 20.00 mL of an unknown solution of a monoprotic acid, it is titrated with 0.1093 M sodium hydr

Elanso [62]

Answer:

d) 0.1202 M

Explanation:

Let's consider the neutralization reaction between NaOH and a generic monoprotic acid.

NaOH + HA → NaA + H₂O

The used volume of NaOH is 41.63 mL - 19.63 mL = 22.00 mL. The moles of NaOH are:

22.00 × 10⁻³ L × 0.1093 mol/L = 2.405 × 10⁻³ mol

The molar ratio of NaOH to HA is 1:1. The moles of HA that reacted are 2.405 × 10⁻³ moles.

The molar concentration of HA is:

2.405 × 10⁻³ mol / 20.00 × 10⁻³ L = 0.1202 M
