Half Life period of first order reaction Solution

STEP 0: Pre-Calculation Summary

Formula Used

Half Life Period = ln(2)/Rate Constant
t_0.5 = ln(2)/K_h
This formula uses 1 Functions, 2 Variables

Functions Used

ln - The natural logarithm, also known as the logarithm to the base e, is the inverse function of the natural exponential function., ln(Number)

Variables Used

Half Life Period - (Measured in Second) - Half Life Period is the time required for 50 percent completion of a first order reaction.
Rate Constant - (Measured in Hertz) - Rate Constant is the coefficient of proportionality relating the rate of a chemical reaction at a given temperature to the concentration of reactant or product.

STEP 1: Convert Input(s) to Base Unit

Rate Constant: 1E-06 Hertz --> 1E-06 Hertz No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

t_0.5 = ln(2)/K_h --> ln(2)/1E-06

Critical free energy for nucleation

LaTeX Go Critical free energy = 16*pi*Surface free energy^3*Melting temperature^2/(3*Latent Heat of Fusion^2*Undercooling value^2)

Critical radius of nucleus

LaTeX Go Critical radius of nucleus = 2*Surface free energy*Melting temperature/(Latent Heat of Fusion*Undercooling value)

Volume free energy

LaTeX Go Volume free energy = Latent Heat of Fusion*Undercooling value/Melting temperature

Critical radius of nucleus (from volume free energy)

LaTeX Go Critical radius of nucleus = -2*Surface free energy/Volume free energy

Use of Half-life period

Half-life period or half-life of a radioactive element can be used to estimate the amount of radioactive element left out after a given time. Half-life is constant over the lifetime of an exponentially decaying quantity, and it is a characteristic unit for the exponential decay equation. In general, the percent of radioactive element left out is given by 100/(2^n), where n is the number of half-lives elapsed.
