Question

For a reaction, C2H4 (g) + H2(g) → C2H6 (g), rate = 5.5 x 10-14 [C2H4).
Write the unit of rate constant.
Calculate its half-life (t1/2).​

Answer 1

Answer:

here k=5.5*10^-14 is given

t1/2 =0.693/k

=0.693/5.5*10^-14

for Unit of rate constant you may refer to part 1 book of chemistry 12 chapter chemical kinetics
