OTHERMOCHEMISTRY Using specific heat capacity to find temperature change 84°F Sunny A chemical reaction takes place inside a flask submerged in a water bath. The water bath contains 5.20 kg of water at 33.7 °C. During the reaction 84.5 kJ of heat flows out of the flask and into the bath. Calculate the new temperature of the water bath.

In a study of the conversion of methyl isonitrile to acetonitrile in the gas phase at 250 °C CH3NC(g) CH3CN(g) the concentration of CH3NC was followed as a function of time. It was found that a graph of In[CH3NC] versus time in seconds gave a straight line with a slope of -4.20×10s and a y-intercept of -2.27 . Based on this plot, the reaction is vJorder in CH3NC and the rate constant for the reaction is

Sodium chlorate crystals are easy to grow in the shape of cubes by allowing a solution of water and sodium chlorate to evaporate slowly. a. If V is the volume of such a cube with side length x, calculate dV/dx when x = 3 mm and explain its meaning (be specific). b. Show that the rate of change of the volume of a cube with respect to its edge length is equal to half the surface area of the cube.
