PV = nRT
P = 157 kPa = 157 × 10³ Pa
V = 265 ml = 0.265 l
T = 20°C = 293 K
m = 0.479 g
PV•M = mRT
M = (mRT)/(PV)
M = 0.479 g × 8.314 kPa.l/(mol.K) × 293 K / (157 kPa × 0.265 l)
M ≈ 28.04579 g/mol.
Hence, the Molar Mass of Dinitrogen or Nitrogen Gas is 28 g.
First, we have to correct the equation in the question to b(g)⇆ 1/2 A(g)
at the first equation A(g)⇆ 2 B(g) so,
Kc = [B]^2 [ A] = 0.03
by reverse the equation 2B⇆ A
∴ Kc(original) = [A] / [B]^2
= 1/0.03 = 33 M^-1
and the new equation B⇆ (1/2) A
So, the new Kc = √Kc(original = √33
∴ KC = 5.7
Answer:
C-H-O is the answer for this one
The correct answer is option D. i.e. <span>pressure, temperature, or concentration.
Equilibrium reactions can involve
1) changes in the temperature conditions - high or low or exothermic or endothermic.
2) Pressure - By increasing or decreasing the pressure
3) Concentration - the changes in concentration take place in either products side or reactants side.
