Time for Completion of First Order Reaction Solution

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

FIRST Step Consider the formula

t completion = \frac{2.303}{k first} \cdot \log 10 (\frac{C AO}{ax})

Next Step Substitute values of Variables

∴

t completion = \frac{2.303}{0.52s⁻¹} \cdot \log 10 (\frac{10mol/L}{8mol/L})

Next Step Convert Units

∴

t completion = \frac{2.303}{0.52s⁻¹} \cdot \log 10 (\frac{10000mol/m³}{8000mol/m³})

Next Step Prepare to Evaluate

∴

t completion = \frac{2.303}{0.52} \cdot \log 10 (\frac{10000}{8000})

Next Step Evaluate

∴

t completion = 0.429198712997771s

LAST Step Rounding Answer

∴

t completion = 0.4292s
