NEET Chemistry Question (2026) — Solution

Step-by-step solution

The relation between K_p and K_c is given by K_p = K_c(RT)^ n_g , where n_g is the difference between the number of moles of gaseous products and gaseous reactants. For K_p K_c, n_g must be non-zero. For H _2 O (g) + CO (g) H _2 (g) + CO _2 (g) , n_g = 2 - 2 = 0 K_p = K_c For N _2 (g) + 3 H _2 (g) 2 NH _3 (g) , n_g = 2 - 4 = -2 K_p K_c For H _2 (g) + I _2 (g) 2 HI (g) , n_g = 2 - 2 = 0 K_p = K_c For N _2 (g) + O _2 (g) 2 NO (g) , n_g = 2 - 2 = 0 K_p = K_c Answer: N _2 (g) + 3 H _2 (g) 2 NH _3 (g)
