Answer:
The initial concentration of ethanal was 0.1590 mol/L.
Explanation:
Integrated rate law for second order kinetic:
k = Rate constant =
t = Time elapsed = 50.0 s
=initial concentration of ethanal
[A] = Concentration of ethanal left after time t = 0.151 mol/L
On substituting the value:
The initial concentration of ethanal was 0.1590 mol/L.
