What is the final temperature when 150 mL of water at 90,0 C is added to 100.0 mL of water
How do you find the concentrations of the individual reactants that are part of the compounds? As far as the relative rate, I don't understand how to find m, n, and p in the equation: relative rate = k' (I-)^m(BrO3-)^n(H+)^p.
Steam at 3MPa and 300oC exits a boiler and goes into a high pressure turbine in which it is expanded to 300kPa. The steam is then sent back to the boiler (constant pressure heat exchanger) and reheated to 300oC.
