Variation of Equilibrium Constant with Temperature at Constant Pressure Solution

Follow our step by step solution on how to calculate Variation of Equilibrium Constant with Temperature at Constant Pressure?

FIRST Step Consider the formula

K 2 = K 1 \cdot \exp ((\frac{ΔH}{[R]}) \cdot (\frac{T 2 - T abs}{T abs \cdot T 2}))

Next Step Substitute values of Variables

∴

K 2 = 0.026 \cdot \exp ((\frac{32.4KJ/mol}{[R]}) \cdot (\frac{310K - 273.15K}{273.15K \cdot 310K}))

Next Step Substitute values of Constants

∴

K 2 = 0.026 \cdot \exp ((\frac{32.4KJ/mol}{8.3145}) \cdot (\frac{310K - 273.15K}{273.15K \cdot 310K}))

Next Step Convert Units

∴

K 2 = 0.026 \cdot \exp ((\frac{32400J/mol}{8.3145}) \cdot (\frac{310K - 273.15K}{273.15K \cdot 310K}))

Next Step Prepare to Evaluate

∴

K 2 = 0.026 \cdot \exp ((\frac{32400}{8.3145}) \cdot (\frac{310 - 273.15}{273.15 \cdot 310}))

Next Step Evaluate

∴

K 2 = 0.141732100801536

LAST Step Rounding Answer

∴

K 2 = 0.1417
