What is the surface area of a hemisphere? Provide a derivation of Equation 4, noting the assumptions that are needed. Suppose that two quantities, x and y, are related by the formula y-kxb, where k and b are constants. A formula of this form is known as a power law. In some experiment, the parameter x is varied and for each value of x a corresponding y value is measured. Explain how to plot a graph of this power law...

ln(k) = -E_a/R 1/T + ln(A) A plot of ln (k)versus 1/T result in a straight line with a slope = -E_a/R. The value of E_a can then be calculated using the value of R and to the slope of the line. This experiment uses the Arrhenius equation, which relates the temperature and specific reaction rate constant to determine the activation energy for the crystal violet reaction. The reaction will be performed at different temperatures. Once the order of reaction...
