For which of the following reactions,

{K_p} = {K_c}

View answer and explanation

Correct option: B

{\mathrm{N}_2} + {\mathrm{O}_2}\leftrightharpoons2\mathrm{NO}

Option B (

{\mathrm{N}_2} + {\mathrm{O}_2}\leftrightharpoons2\mathrm{NO}

) is correct because in this reaction, the number of moles of gaseous reactants equals the number of moles of gaseous products, making
