General Science / Chemistry Class 10th MCQs — Multiple-choice practice
جس نظام کے لیے توازن مستقل ہے، کے سی میں ارتکاز کی اکائیاں ہیں۔
- A. CO2(g) + H3(g) ⇌ CO + H2O(l)
- B. N2(g) + 3H2(g) ⇌ 2NH3(g)
- C. H2(g) +12(g) ⇌ 2HI(g)
- D. N2(g) + 02(g) ⇌ 2NO
Correct answer
N2(g) + 3H2(g) ⇌ 2NH3(g)
Explanation
Explanation The equilibrium constant, Kc, has units of concentration for the reaction: N2(g) + 3H2(g) ⇌ 2NH3(g) This reaction involves a change in the number of moles of gas on both the reactant and product sides, specifically: 4 moles (reactants) ⇌ 2 moles (products)
