Le Chatelier’s Principle and Chemical Equilibrium

Question

Nitrosyl bromide, NOBr(g), decomposes according to the equation

NOBr(g) -------> NO(g)+ ½ Br₂(g)

a. If the equilibrium constant Kp= 0.15 at 350^oC, will any net reaction occur if 1.2 atm NOBr, 0.7 atm NO and 0.6 atm Br₂ are mixed at 350^oC?

Answer 1

𝑸=[𝑩𝒓_𝟐]^𝟏/𝟐[𝑵𝑶] / [𝑵𝑶𝑩𝒓]

=(𝟎.𝟔 𝒂𝒕𝒎)^𝟏/𝟐(𝟎.𝟕 𝒂𝒕𝒎) / (𝟏.𝟐 𝒂𝒕𝒎)

=𝟎.𝟒𝟓𝟐

Q > kp

Reverse reaction will occur
