Answer:
a. [HI]² / [I₂] . [H₂]
b. Kc = 46.9
c. This is an homogeneous reaction
Explanation:
The equilibrium is this:
H₂ (g) + I₂ (g) ⇄ 2HI (g)
Eq. 0.102M 0.00183M 0.0963M
The expression for Kc will be:
Kc = [HI]² / [I₂] . [H₂]
Kc = 0.0963² / 0.00183 . 0.102
Kc = 46.9
The reaction is homegeneous, because all the reactants and the product are at the same phase. In this case, as the reaction is homogeneous, the speed of reaction is not affected by the exposed surface area.
If it was an heteregeneous reaction, it would depend on the area of the surface exposed to the mixture of reaction. The heterogeneous reaction are in a different phase, for example a catalyst in a different phase as the reactants.
Weak intermolecular forces.
Less energy is therefore needed to overcome the weak intermolecular forces between the molecules, to separate out.
Hope it helped!
Answer:
450 ft is equal to 137. 16 metres.
1 foot is equal to 0.3048
so you'll just multiply 450 to 0.3048
so the answer is 137.16
