Phosphorescence Rate Constant Solution

Follow our step by step solution on how to calculate Phosphorescence Rate Constant?

FIRST Step Consider the formula

K ph = \frac{R p}{[M T]}

Next Step Substitute values of Variables

∴

K ph = \frac{15750mol/L*s}{6.2E-5mol/L}

Next Step Convert Units

∴

K ph = \frac{1.6E+7mol/m³*s}{0.062mol/m³}

Next Step Prepare to Evaluate

∴

K ph = \frac{1.6E+7}{0.062}

Next Step Evaluate

∴

K ph = 254032258.064516Hz

Next Step Convert to Output's Unit

∴

K ph = 254032258.064516rev/s

LAST Step Rounding Answer

∴

K ph = 2.5E+8rev/s

How to Evaluate Phosphorescence Rate Constant?

Phosphorescence Rate Constant evaluator uses Rate Constant of Phosphorescence = Rate of Phosphorescence/Concentration of Triplet State to evaluate the Rate Constant of Phosphorescence, The Phosphorescence Rate Constant formula is defined as the rate at which phosphorescence occurs during emission from triplet to singlet state. It is the constant for emission of light from triplet-excited states, in which the electron in the excited orbital has the same spin orientation as the ground-state electron. Rate Constant of Phosphorescence is denoted by K_ph symbol.
