The irreversible elementary reaction 2A  B takes place in the gas phase of an isothermal 50 L tubular (CSTR) reactor at 760 Torr. Product B is the only condensable component in the system. The vapor pressure of B at 600K is 150 Torr. What is the conversion of A when condensation occurs? What is the initial flow of A and flow rate of B leaving the reactor at XA = 25%? What is the initial flow of A at XA = 80%? Additional Data: To = 300 K, T = 600 K, k1 = 100 L/mol-sec, k-1 = 2/sec,

Smog is the term used to describe the combination of fog and smoke

Agroup of students is studying convection current. they fill two identical balloons with the same amount of helium. one balloon is placed in a freezer and the other is in an area with warm air. after 10 minutes, the balloon are released from a height of 1 meter. which of the following to the students most likely observe? a) the warm balloon expands and rises. the cold balloon shrinks and sinks b) the balloon both rise. the cold balloon is larger than the warm balloon c) the cold balloon expands and rises. the warm balloon shrinks and sinks d) the balloon rise at the same rate. both balloons are the same size
