Answer to Question #288577 in Organic Chemistry for Pranali

Question

A mixture containing C₂H₅Br, HBr, C₂H₆, and Br₂, all at an initial partial pressure of 3.32 atm, is allowed to achieve equilibrium according to the equation below. At equilibrium, the partial pressure of Br₂ is observed to have increased by 0.14 atm. Determine K_p for this chemical equilibrium.

C₂H₅Br(g) + HBr(g) ⇌ C₂H₆(g) + Br₂(g)

Answer 1

3.32-0.6=2.72

0.14+0.6= 0.74

2.72-0.74

= 1.98
