The value of the second order rate constant at 80 degrees celcius for - delta[BrO-]/delta[t] was found to be 0.056 L/mole/second. What is the rate constant when the rate law is written delta[BrO3-]/delta[t]? Or delta[Br-]/delta[t]?
What are the concentrations of HSO4-, SO42-, and H+ in a 0.27 M KHSO4 solution? (Hint: H2SO4 is a strong acid; Ka for HSO4- = 1.3 10-2.).
The enthalpy change for any reaction can be obtained by subtracting the sum of the enthalpy changes of formation of the reactants from the sum of the enthalpy changes of formation of the products.
Calculate the dryness fraction of the steam between the separator and the throttle, and hence the dryness fraction of the steam being bled from the system.
