In a reaction involving the synthesis of ammonia by Haber's process, N2+3H2⇌2NH3\text{N}_2 + 3\text{H}_2 \rightleftharpoons 2\text{NH}_3 , the rate of reaction was measured as =2.5×10−4 mol L−1 s−1= 2.5 \times 10^{-4} \text{ mol L}^{-1} \text{ s}^{-1} . The rate of change of conc. of H2\text{H}_2 will be (A) 1.25×10−4 mol L−1 s−11.25 \times 10^{-4} \text{ mol L}^{-1} \text{ s}^{-1} (B) 2.50×10−4 mol L−1 s−12.50 \times 10^{-4} \text{ mol L}^{-1} \text{ s}^{-1} (C) 7.5×10−4 mol L−1 s−17.5 \times 10^{-4} \text{ mol L}^{-1} \text{ s}^{-1} (D) 5.0×10−4 mol L−1 s−15.0 \times 10^{-4} \text{ mol L}^{-1} \text{ s}^{-1}
