Answer:
109.09°C
Explanation:
Given that:
the capacity of the cooling car system = 5.6 gal
volume of solute = volume of the water; since a 50/50 blend of engine coolant and water (by volume) is used.
∴
Afterwards, the mass of the solute and the mass of the water can be determined as shown below:
mass of solute =
On the other hand; the mass of water =
Molarity =
=
= 17.757 m
≅ 17.76 m
∴ the boiling point of the solution is calculated using the boiling‑point elevation constant for water and the Molarity.
where,
= 0.512 °C/m
= 100°C + 17.56 × 0.512
= 109.09 °C
Answer: Rate law=, order with respect to A is 1, order with respect to B is 2 and total order is 3. Rate law constant is
Explanation: Rate law says that rate of a reaction is directly proportional to the concentration of the reactants each raised to a stoichiometric coefficient determined experimentally called as order.
k= rate constant
x = order with respect to A
y = order with respect to A
n = x+y = Total order
a) From trial 1: (1)
From trial 2: (2)
Dividing 2 by 1 :
therefore y=2.
b) From trial 2: (3)
From trial 3: (4)
Dividing 4 by 3:
, x=1
Thus rate law is
Thus order with respect to A is 1 , order with respect to B is 2 and total order is 1+2=3.
c) For calculating k:
Using trial 1:
