Answer : Linear
Explanation : Hydrogen Cyanide (HCN) when drwan in the Lewis diagram shows carbon atom at the center with no lone electron pairs.
The carbon and nitrogen atoms are bonded through a triple bond which counts as "one electron pair".
The molecule has two electron pairs in all and appears to be linear.
Also, according to the VSEPR theory; the electron clouds on atoms around the carbon will try to repel each other.
They will get pushed apart, which gives HCN molecule a linear molecular geometry or shape.
The bond angle that is developed will be 180 degrees since it has a linear molecular geometry of HCN. The hybridisation observed in this molecule is SP.
<u>Answer:</u> The rate law expression is and value of 'k' is
<u>Explanation:</u>
Rate law is defined as the expression which expresses the rate of the reaction in terms of molar concentration of the reactants with each term raised to the power their stoichiometric coefficient of that reactant in the balanced chemical equation.
For the given chemical equation:
Rate law expression for the reaction:
where,
a = order with respect to nitrogen monoxide
b = order with respect to oxygen
- <u>Expression for rate law for first observation:</u>
....(1)
- <u>Expression for rate law for second observation:</u>
....(2)
- <u>Expression for rate law for third observation:</u>
....(3)
Dividing 1 from 2, we get:
Dividing 1 from 3, we get:
Thus, the rate law becomes:
Now, calculating the value of 'k' by using any expression.
Putting values in equation 1, we get:
Hence, the rate law expression is and value of 'k' is
