Answer to Question #184296 in General Chemistry for Rupakshi chauhan

Question

In the electrowinning process, a Metallurgical/Chemical Engineer uses an Infrared (IR) camera to detect metallurgical short-circuits (hot spots) over the anodes and cathodes. Given that the mass of an electron is 9.109× 1031 𝐾𝑔 and Rydberg’s constant is 1.090×107 𝑚−1, determine the energy (in MJ) applied when 5 mol of IR photons having a wavelength of 3 nm is used in the copper electrolysis process.

Answer 1

Energy Applied ;

$=7.61×10 ^{6}MJ$
