Next Step Substitute values of Constants

∴

A factor-secondorder = \frac{0.51L/(mol*s)}{\exp (- \frac{197.3778J/mol}{8.3145 \cdot 84.9999K})}

Next Step Convert Units

∴

A factor-secondorder = \frac{0.0005m³/(mol*s)}{\exp (- \frac{197.3778J/mol}{8.3145 \cdot 84.9999K})}

Next Step Prepare to Evaluate

∴

A factor-secondorder = \frac{0.0005}{\exp (- \frac{197.3778}{8.3145 \cdot 84.9999})}

Next Step Evaluate

∴

A factor-secondorder = 0.000674313004097083m³/(mol*s)

Next Step Convert to Output's Unit

∴

A factor-secondorder = 0.674313004097083L/(mol*s)

LAST Step Rounding Answer

∴

A factor-secondorder = 0.6743L/(mol*s)
