Compute the vapor pressure of a solution prepared by dissolving .500 mol of a non-volatile solute in 275g of hexane M=86.18 g/mol at 49.6 C. P(hexane) = 400 torr at 49.6C
What must be the reaction temperature if a rate of 1.000 x 10^-9 M/s is required and [C] must be kept at 0.03000M. What must be the value of k to achieve the necessary rate?
calculate the percent yield based upon the amount of maleic anhydride used. use the molecular weight of one repeating monomer unit for the weight of the product.
or each of the following cases, briefly explain whether the action causes net reaction from left to right, right to left, or no net reaction. Also, state whether the equilibrium partial pressure of NH3 increases, decreases or stays the same. (a) i..
