a first order parallel reaction given as"a-----b and c .given that k1 is rate constant for formation of b and k2 is rate constant for c.k1=1.3 * 10 to power -5 ,sec to power -1.also k1\k2=1\9.find conc.ratio of c to a if an experiment is allowed to start with only a for 1 hr.

A---->B     k1

A---->C     k2

d[B]/dt = k1*[A]      d[B] = k1*[A] dt

d[C]/dt = k2*[A]      d[C] = k2*[A] dt

therefore [B]/[C] = k1/k2 = 1/9

[A] = [B]+[C]

[A]/[C] = [B]/[C] + 1 = 1/9 +1 = 11/9

The mass ofa nonvolatile solute of malar mass 40g/mol that should be dissolved in114g of octane to lower its vapour 20% is......... a) 10 g b)11.4 gc)9.8 g d)12.8 g
From partial pressure for non volatile solute formulae: (P – xP)/P = nA/nB (P – 0.2P)/P = (w/40)/(114/114) 0.8 = w/40 w = 32 g.

the dipole moment of hydrogen chloride with bond distance 127 pm is 1.03D.the % of ionic character of its bond is
We know the dipole formulae that is: Dipole Moment = charge x distance D = 1.602 x 10^-19 x 127 x 10^-12 x 1/(3.36 x 10^-30) = 6 pm ( approx.) ionic charcter % = > 1/6 * 100 => 16.66 %
