Areaction chamber contains a mixture of n2 and n in equilibrium at a specified temperature and pressure (i. e., the reaction is n2 leftarrow rightarrow 2n). now the temperature is increased at constant pressure. the number of moles of n2 in the system: does not change increases decreases cannot be determined from the given information

An engine, weighing 3000 n, is supported on a pedestal mount. it has been observed that the engine induces vibration into the surrounding area through its pedestal at the maximum operating speed. determine the stiffness of the dynamic vibration absorber spring in (n/m) that will reduce the vibration when mounted on the pedestal. the magnitude of the exciting force is 250 n, and the amplitude of motion of the auxiliary mass is to be limited to 2 mm note: in this question type-in right numbers, no decimals, no fractions, no unit. approximate to right number if needed
