Answer: Length for line A  = 36mm

Length for line B = 22mm

Length for line C = 12.5mm

Length for line D = 7mm

Explanation: To measure the length on the scale, the distance between the front edge that is the blue line and the last edge that is the dotted line for each letter is calculated.

The major division for this scale is 1 cm and minor division for this scale is 0.1 cm.

Conversion factor: 1 cm = 10 mm

  • Distance from the front line to the dotted line of A is 3.6cm which makes it as 36mm.
  • Distance from the front line to the dotted line of B is 2.2cm which makes it as 22mm.
  • Distance from the front line to the dotted line of C is 1.25cm which makes it as 12.5mm.
  • Distance from the front line to the dotted line of D is 0.7cm which makes it as 7mm.

A possible mechanism for the overall reaction br2 (g) + 2no (g) → 2nobr (g) is no (g) + br2 (g) nobr2 (g) (fast) nobr2 (g) + no
givi [52]
The overall reaction is:
Br₂(g) + 2 NO(g) ↔ 2 NOBr(g)
rate law = k [Br₂][NO]²

The first step of the overall reaction is:
NO(g) + Br₂(g)   K₁⇄⇄K-1  NOBr₂(g)
rate law 1 = k₁ [Br₂][NO] or 
rate law 2 = k-1 [NOBr₂]

The second step of the overall reaction is:
NOBr₂(g) + NO(g)  →K₂→ 2 NOBr
rate law 3 = k₂[NOBr₂][NO]

So, rate law of overall reaction can be obtained as follows:
(rate law 1)*(rate law 3) / (rate law 2)
= [(k₁[Br₂][NO])* (K₂[NOBr₂][NO])] / k₋₁[NOBr₂]
= [k₁k₂/k₋₁][NO]²[Br₂]
So the correct answer is:
[k₁k₂/k₋₁][NO]² [Br₂]
