Answer:
The activation energy is 7.11 × 10⁴ J/mol.
Explanation:
Let's consider the Arrhenius equation.
where,
k is the rate constant
A is a collision factor
Ea is the activation energy
R is the ideal gas constant
T is the absolute temperature
The plot of ln k vs 1/T is a straight line with lnA as intercept and -Ea/R as slope. Then,
Answer:
(1) 0.035 × 10²³
Explanation:
Step 1: Calculate the mass of Fe in 100 g of Haemoglobin
Haemoglobin contains 0.33% Fe, that is, there are 0.33 g of Fe per 100 grams of Haemoglobin.
100 g Hb × 0.33 g Fe/100 g Hb = 0.33 g Fe
Step 2: Convert 0.33 g of Fe to moles
We will use the molar mass of Fe (55.85 g/mol).
0.33 g × 1 mol/55.85 g = 5.9 × 10⁻³ mol
Step 3: Convert 5.9 × 10⁻³ moles of Fe to atoms
We will use Avogadro's number.
5.9 × 10⁻³ mol × 6.02 × 10²³ atoms/1 mol = 3.5 × 10²¹ atoms (= 0.035 × 10²³)
