Answer:
0.1056 mole
Explanation:
As Sally knows that the charge on the metal ion is n = +2
In that compartment
The volume of the taken in that compartment = 6.380 mL
So, the number of moles of
= 52.82 m mol
= 0.05280 mol
But n = 2
Therefore, moles of = 2 x moles of
= 2 x 0.05282
= 0.1056 mole
Answer:
30 kJ
Explanation:
Arrhenius equation is given by:
Here, k is rate constant, A is Pre-exponential factor, Ea is activation energy and T is temperature.
taking natural log of both side
ln k = ln A - Ea/RT
In Arrhenius equation, A, R and T are constant.
Therefore,
is the lowering in activation energy by enzyme,
R = 8.314 J/mol.K
T = 37°C + 273.15 = 310 K
