Lyrx [107]

<u>Answer: </u>0.0285 moles of HCl is present in given amount of solution.

<u>Explanation:</u>

Molarity is defined as the amount of solute expressed in the number of moles present per liter of solution. The units of molarity are mol/L. The formula used to calculate molarity:

\text{Molarity of solution}=\frac{\text{Moles of solute}\times 1000}{\text{Volume of solution (mL)}} .....(1)

Given values:

Molarity of HCl = 0.453 M

Volume of solution = 62.85 mL

Putting values in equation 1, we get:

0.453mol/L=\frac{\text{Moles of HCl}\times 1000}{62.85}\\\\\text{Moles of HCl}=\frac{0.453\times 62.85}{1000}=0.0285moles

Hence, 0.0285 moles of HCl is present in given amount of solution.

What is the value of k for this aqueous reaction at 298 k?
TEA [102]

Answer : The complete question is attached in answer.

The value of K will be = 2 X10^{-5}


Explanation : We can use the formula as;


∆G = -RT ln K


on rearranging we get, K = e^({-deltaG/RT})

Therefore, we get,

∆G/RT = (26.81 kJ/mol ) / (0.008314 kJ/mol-K) X (298K) = 10.82


So, K = e^{-10.82}

Therefore, K = 2 X 10^{-5}
