What will be the concentration of 'A' at time t, if n1 = 1 and n2 = 2? — Chemical Kinetics Chemistry Question

💡 Solution & Explanation

Using n1 = 1 and n2 = 2, total moles = a [2 + (1 - 2)e^-kt] = a [2 - e^-kt]. Volume Vt = V0 [2 - e^-kt]. Concentration of A = (moles of A) / Vt = (a·e^-kt) / (V0 [2 - e^-kt]). Since [A]0 = a / V0, [A]t = [A]0 (e^-kt / (2 - e^-kt)). Therefore, correct answer is B.
