the volume v=4/3πr3 of a spherical balloon changes with the radiusa) at what rate (ft3/ft) does the volume change with respect to the radius when r=2ft?(type an exact answer in terms of π)b)using the rate from part a, by approximately how much does the volume increase when the radius changes from 2 to 2.4ft?
The irreversible reaction A+B -C takes place isothermally and with no volume change. The kinetic rate expression follows that of an elementary reaction. Make plots of the ratio of the radius, Re, of a spherical CSTR to the length, L, of a cylindrical plug flow reactor of constant cross section of radius Rp as a function of conversion, when the ratio Re /Rp varies from 1 to 10. The feed to the reactors is an equimolar mixture of A and...
PART A ) Consider the reaction:4A + 6B → 3C + 2D If the rate of change of D at a given point in time is 0.180 M/s, what is the rate of change of B at this same time?
