Drug Rate Entering Body Solution

Follow our step by step solution on how to calculate Drug Rate Entering Body?

FIRST Step Consider the formula

k a = \frac{\ln (2)}{t a/2}

Next Step Substitute values of Variables

∴

k a = \frac{\ln (2)}{0.69s}

Next Step Prepare to Evaluate

∴

k a = \frac{\ln (2)}{0.69}

Next Step Evaluate

∴

k a = 1.0045611312463s⁻¹

Next Step Convert to Output's Unit

∴

k a = 3616.42007248667h⁻¹

LAST Step Rounding Answer

∴

k a = 3616.4201h⁻¹
