Answer:
The heat of the solution of salt is 1.66.11 J/g.
Explanation:
Mass of the water = m = 46.52 g
Initial temperature of the water =
Final temperature of the water =
The specific heat of water, c = 4.180 J/gºC
Heat associated with water on dissolving salt: q
Negative sign means that heat was lost by water on an addition of a salt.
Heat released on dissolving of salt = -Q = 748.65 J
Mass of salt added = 4.5069 g
Heat of the solution of salt :
=
The heat of the solution of salt is 1.66.11 J/g.
Answer:
rate = k[A][B] where k = k₂K
Explanation:
Your mechanism is a slow step with a prior equilibrium:
(The arrow in Step 1 should be equilibrium arrows).
1. Write the rate equations:
2. Derive the rate law
Assume k₋₁ ≫ k₂.
Then, in effect, we have an equilibrium that is only slightly disturbed by C slowly reacting to form D.
In an equilibrium, the forward and reverse rates are equal:
k₁[A][B] = k₋₁[C]
[C] = (k₁/k₋₁)[A][B] = K[A][B] (K is the equilibrium constant)
rate = d[D]/dt = k₂[C] = k₂K[A][B] = k[A][B]
The rate law is
rate = k[A][B] where k = k₂K
