Energy of Photochemical Reaction Solution

Follow our step by step solution on how to calculate Energy of Photochemical Reaction?

FIRST Step Consider the formula

E = [Avaga-no] \cdot [hP] \cdot f

Next Step Substitute values of Variables

∴

E = [Avaga-no] \cdot [hP] \cdot 90Hz

Next Step Substitute values of Constants

∴

E = 6E+23 \cdot 6.6E-34 \cdot 90Hz

Next Step Prepare to Evaluate

∴

E = 6E+23 \cdot 6.6E-34 \cdot 90

Next Step Evaluate

∴

E = 3.59128138198489E-08J

LAST Step Rounding Answer

∴

E = 3.6E-8J
