Answer to Question #143094 in General Chemistry for Jushoa

Question

Suppose that a batch of parts is played with copper in an electrolytic bath running at 0.15V and 15A for exactly 2 hrs. What is the energy cost of this process if the electric utility charges the company Php. 4.05/KW-hr.

Answer 1

Energy = VIt

Time t in seconds = 2hr which is equal to 7200sec

Energy = 0.15×15×7200

Energy = 16200 joules = 16.2 KW-hr

Energy cost = 16.2×4.05 =65.61
