In an effort to determine the cause of low yields from a reactor, a tracer study was conducted. An amount N0=3.80kg of an inert tracer A was injected into the feed port of the 1.9m3 reactor. The volumetric flow rate was constant at v0=3.1L/s. The following tracer-response data were acquired: Calculate values of E(t),tm; and 2 for flow through the vessel
