Half Time Completion of First Order Reaction Solution

Follow our step by step solution on how to calculate Half Time Completion of First Order Reaction?

FIRST Step Consider the formula

t 1/2 = \frac{0.693}{k first}

Next Step Substitute values of Variables

∴

t 1/2 = \frac{0.693}{0.52s⁻¹}

Next Step Prepare to Evaluate

∴

t 1/2 = \frac{0.693}{0.52}

Next Step Evaluate

∴

t 1/2 = 1.33268974482741s

LAST Step Rounding Answer

∴

t 1/2 = 1.3327s
