The IR spectrum of aldehyde compound will not show evidence of hydrogen bonding. The Infrared (IR) spectrum involves the interaction of infrared radiation with matter. It is used to study and identify chemicals and their properties. Evidence of hydrogen bonding is not shown due to lack of molecular contact.
The equilibrium reaction is
2 NOBr ⇄ 2 NO + Br₂
The initial molarity of NOBr is 0.174 mol/1 L = 0.174 M. Let's apply the ICE approach which stands for Initial-Change-Equilibrium.
2 NOBr ⇄ 2 NO + Br₂
I 0.174 0 0
C -2x +2x +x
----------------------------------------------------
E 0.174-2x 2x x
Since E for Br₂ is 1.79*10⁻² M, then that means x = 1.79*10⁻² M. We can compute E for the other compounds.
E for NOBr = 0.174 - 2(1.79*10⁻²) = 0.1382 M
E for NO = 2(1.79*10⁻²) = 0.0358 M
The expression for Kc according to the reaction is:
Kc = [NO]²[Br₂]/[NOBr]²
Kc = [0.0358]²[1.79*10⁻²]/[0.1382]²
<em>Kc = 1.2×10⁻³</em>
