How to monitor rate with a colorimeter?
Plot a calibration curve after zeroing and measuring absorbance readings
What does increasing the temp do to the boltzmann distribution?
Shifts it to the right, increasing proportion of particles that exceed Ea
How does doubling the initial conc in zero order affect half life?
Doubling initial conc doubles half life as rate is constant
How does doubling the initial conc in first order affect half life?
Doubling initial conc has no effect as it is always constant
How does doubling the initial conc in second order affect half life?
Halves half life as rate is proportional to the square of the conc
What is half life?
Time it takes for half of a reactant to be used up
With combustion cycles what do you do?
Subtract. In a combustion cycle, subtract the combustion value of the product from the reactant:
ΔH = ΔHc(reactant) − ΔHc(product)
With formation cycles what do you do?
△H = products - reactants
What is the value of enthalpy of combustion always?
Negative value
