The
equilibrium constant is a value which represents the equilibrium of a reaction.
It is a reaction quotient when the reaction reached equilibrium. The reaction in the system is expressed as:
<span>H2 + I2 = 2HI
we express Keq as follows:
Keq = [HI]^2 / [H2] [I2]
Where the terms represents the concentrations of
the substances involved. THe concentrations are as follows:</span>
<span>H2 = 0.763 ( 1 / 18.02) / 3.67 = 0.0115 M</span>
<span>I2 = 96.9 ( 1 / 253.8) / 3.67 = 0.1040 M</span>
<span>HI (at equilibrium) = 90.4 ( 1 / 127.91) / 3.67 = 0.1956 M</span>
<span>
By the ICE table, we can calculate the
equilibrium concentrations,
H2 I2 HI
I 0.0115 0.1040 0
C -x -x +2x
-----------------------------------------------------------
E 0.0115-0.0963 0.1040-0.0963 0.1926 ===> x = 0.0963
Keq = (</span>0.1926<span>)^2 / (0.0077) (0.0848)
Keq = 56.81</span>
Answer:
Vaporization and Sublimation
Explanation:
Answer:
The third option is what a tsunami is.
Explanation:
When the volume is 450 cm3 so the boat will displace 450 g.
so we have 450 g - 14.5g = 435.5 left
so to get how many pennies can be added to the boat before it sinks can be determined by:
divided the mass for the one penny:
no.of Penny = 435.5 / 2.5g
= 174.2
∴ the boat will float with 174 pennies and will start to sink with 175
