Question For an elementary reaction \( 2 \mathrm{~A} \underset{\mathrm{k}_{2}}{\stackrel{\mathrm{k}_{1}}{\rightleftharpoons}} \mathrm{B} \). The rate of disappearance of \( \mathrm{A} \) is equal to
(A) \( \frac{2 \mathrm{k}_{1}}{\mathrm{k}_{2}}[\mathrm{~A}]^{2} \)
(B) \( -2 \mathrm{k}_{1}[\mathrm{~A}]^{2}+2 \mathrm{k}_{2}[\mathrm{~B}] \)
(C) \( 2 \mathrm{k}_{1}[\mathrm{~A}]^{2}-2 \mathrm{k}_{2}[\mathrm{~B}] \)
(D) \( \left(2 \mathrm{k}_{1}-\mathrm{k}_{2}\right)[\mathrm{A}] \)📲PW App Link - https://bit.ly/YTAI_PWAP 🌐PW Website - https://www.pw.live
