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:Binary acids are acids composed of two atoms ,a hydrogen element and non metal element .Binary acids are also known as Hydracids.
Explanation:For example
Hydrochloric acid (HCl), hydrofluoric acid (HF), and hydroiodic acid (HI) are all binary acids.
Answer:
A reaction mechanism is the sequence of elementary steps by which a chemical reaction occurs. A reaction that occurs in two or more elementary steps is called a multistep or complex reaction. ... The slowest step in a reaction mechanism is known as the rate-determining step.
I believe this is the answer
