Answer:
Option c) The measurement of how much solute can be dissolved in a liter of solvent.
Explanation:
The concentration of a solution can be defined as the amount of solute in 1 litre of the solvent i.e how much of the solute that can dissolve in a litre of the solvent. Mathematically, it can be written as:
Concentration = mole of solute / Volume of solvent
Thus, the unit for the concentration is mole per litre (mol/L)
From the above illustration, we thus say that the concentration of a solution is a measure of how much solute can be dissolved in a liter of solvent.
Generally speaking mechanical energy is energy which physically moves (the object), while the thermal energy is energy from the movement of atoms.
Basically temperature is a measurement of atomic movement (doesn't move object as a whole).
Hence heat.
The rate equation is given as:
k = A e^(- Ea / RT)
Dividing state 1 and state 2:
k1/k2 = e^(- Ea / RT1) / e^(- Ea / RT2)
k1/k2 = e^[- Ea / RT1 - (- Ea / RT2)]
k1/k2 = e^[- Ea / RT1 + Ea / RT2)]
Taking the ln of both sides:
ln (k1/k2) = - Ea / RT1 + Ea / RT2
ln (k1/k2) = - Ea / R (1/T1 - 1/T2)
Since k2 = 4k1, therefore k1/k2 = ¼
ln (1/4) = [- (56,000 J/mol) / (8.314 J / mol K)] (1/273
K – 1/ T2)
2.058 x 10^-4 = 1/273 – 1/T2
T2 = 289.25 K
Answer:
It is called Potassium Hydroxide
