Problem 16

A dam is inclined at an angle of 30 from the vertical and has the shape of an isosceles trapezoid 100 ft wide at the top and 50 ft wide at the bottom and with a slant height of 70 ft. Find the hydrostatic force on the dam when it is full of water.

Step 1 of 3

Chapter 15 Part 2:  The Steady State Approximation: o Two limiting cases:  Low pressure: When [M] is small, k2>k2[M] and rate is 2ndorder  High pressure: When [M] is large, k1[M]>k2 and rate is 1 order  Intermediates follow pseudo first-order kinetics  Effects of temperature on reaction rates: o Many reactions increase rapidly with T  Increase T by 10 degrees, rate doubles o Arrhenius equation states that rate constants depend exponentially on temperature. o k=Ae^-Ea/RT o lnk=lnA-Ea/RT o When plotted with y axis lnk and x axis 1/T, the slope is a negative linear one
