A heavy flywheel, rotating initially at 1500 rpm is allowed to slow down to 1120 rpm in 10.2 minutes due to air and bearing friction. It is then brought to rest by the application of a brake which caused an angular deceleration of 1.15 rad/s2. Calculate
i) the total time in minutes and
ii) the total number of revolutions to come to rest from 1500 rpm
a gas expands and does p-v work on thesurroundings equal to 287 j. at the same time it absorbs 216 j of heat from the
Show that the proton condition for a NH4Cl solution is a linear combination of the mass balance equations and the charge balance equation.
A certain first-order reaction has a rate constant, k, equal to 2.1 x 10-5 at 355 K. If the activation energy for this reaction is 135 kJ/mol compute the value of the rate constant (s-1) at 550 K.
