Question

x to y . in this reaction the concentration of x is 25 mol/lit at time 40min . the concentration of x is 5mol/lit at time 80min ?​

Answer 1

For a first order reaction, (A) → product, the concentration of A changes from 0.1 M to 0.025 M in 40 minutes. The rate of reaction when the concentration ...

For first order reaction, k = 2.303/40 log0.1/0.025 = 2.30340log 4 = 2.30320log 2 = 2.30320 × 0.301 = 0.0347 k = 0.0347 Rate = k[A] Rate = 0.0347 × ...
