Answer:

The average atomic mass of vitellium is 192.11 amu.

Explanation:

The average atomic mass is an average between the masses of all the isotopes, considering their abundance in the nature. It can be calculated using the following expression:

AAM=\frac{\Sigma m_{i} \times ab_{i}  }{100}

where,

m_{i} is the mass of each isotope.

ab_{i} is the abundance in the nature of each isotope.

For <em>vitelium</em>,

AAM=\frac{187.9122amu \times 10.861 + 190.9047amu \times 12.428 + 192.8938 amu\times 76.711 }{100} =192.11amu

2. if 0.20 m fe3 had been used instead of 0.020 m fe3 , how would the numerical value of the rate constant and the activation en
dezoksy [38]

the calculated value is Ea is 18.2 KJ and A is 12.27.

According to the exponential part in the Arrhenius equation, a reaction's rate constant rises exponentially as the activation energy falls. The rate also grows exponentially because the rate of a reaction is precisely proportional to its rate constant.

At 500K, K=0.02s−1

At 700K, k=0.07s −1

The Arrhenius equation can be used to calculate Ea and A.

RT=k=Ae Ea

lnk=lnA+(RT−Ea)

At 500 K,

ln0.02=lnA+500R−Ea

500R Ea (1) At 700K lnA=ln (0.02) + 500R

lnA = ln (0.07) + 700REa (2)

Adding (1) to (2)

700REa100R1[5Ea-7Ea] = 0.02) +500REa=0.07) +700REa.

=ln [0.02/0 .07]

Ea= 2/35×100×8.314×1.2528

Ea =18227.6J

Ea =18.2KJ

Changing the value of E an in (1),

lnA=0.02) + 500×8.314/18227.6

= (−3.9120) +4.3848

lnA=0.4728

logA=1.0889

A=antilog (1.0889)

A=12.27

Consequently, Ea is 18.2 KJ and A is 12.27.
