When N a N O 3 is heated in a closed, oxygen is liberated and N a N O 2 is is left behind. At equilibrium

Options

  1. Aaddition of N a N O 2 favours forward reverse reaction
  2. Baddition of N a N O 2 favours forward reaction
  3. Cincreasing temperature favours forward reaction
  4. Ddecreasing pressure favours reverse reaction

Correct answer

C. increasing temperature favours forward reaction

Step-by-step solution

N a N O 3 ( s ) ⇌ N a N O 2 ( s ) + 1 2 O 2 ( g ) ; Δ H = + v e Also K p = ( P O 2 ) 1 / 2 and thus, addition of N a N O 3 or N a N O 2 has no effect.
