The rate of the following reaction: Radioactive decay of 136 Cs, is characterize

Question

The rate of the following reaction: Radioactive decay of 136Cs, is characterized by the rate constant k = 0.053 day-1. What is the half-life (in days) for this reaction at the same conditions when the initial concentrations are 0.0494 M? (Round your answer to 3 significant figures.)

Hint: The units of the rate constant are linked with the order of reaction.

1) Enter your answer for the concentration expressed in mol/L:

2) Enter your answer for the concentration expressed in molecule/cm3. Round the numeric value to 3 significant figures if present.

The number of significant digits is set to 3

Explanation / Answer

Kt = ln (N/n )

t= ln2 /k=13.07 sec
