Answer:
It is higher than that of water
Explanation:
Because we now know that through experimentation, the new compound has a higher and stronger hydrogen bonds than water, the specific heat capacity will be higher.
Specific heat capacity is the amount of heat needed to raise the temperature of a unit mass of as substance by 1°C.
- This property is a physical property of matter .
- Most physical properties are a function of intermolecular forces in a compound.
- Since hydrogen bond is a very strong intermolecular force, the specific heat capacity will be stronger for the compound discovered.
- This implies that it will require more heat to raise the temperature of a unit mass of this compound by 1°C.
Answer:
0.023
Explanation:
The Arrhenius' equation states that:
Where k is the velocity constant of the reaction, A is the constant of the collisions, Ea is the activation energy (the energy necessary to the molecules have so the reaction will happen), R is the gas constant (8.314 J/molK) and T is the temperature.
This equation is derivated of:
k = pZf
Where
p=fraction of collisions that occur with reactant molecules properly oriented
f=fraction of collisions having energy greater than the activation energy
Z=frequency of collisions
Thus, p*Z = A, and
f =
So, if the energy of the molecules is 12.5 kJ/mol = 12500 J/mol, thus the fraction will be:
f =
f = 0.023
