The Correct Option is C
Solution and Explanation
पद 1: प्रश्न को समझना
यह zero-order kinetics का प्रश्न है।
पद 2: मुख्य सूत्र या दृष्टिकोण
Zero-order: \[ [A]_t=[A]_0-kt \] पद 3: विस्तृत व्याख्या
दिया है: \[ [A]_0=2M \] 75% consumed means: \[ [A]_t=25\%\text{ of }2=0.5M \] अब: \[ 0.5=2-1\times t \] \[ t=1.5min \] पद 4: अंतिम उत्तर
अतः सही विकल्प (C) है।
