Propylene is hydrogenated in a batch reactor: c3h6 g h2 g! c3h8 g equimolar amounts of propylene and hydrogen are fed into the reactor at 25°c and a total absolute pressure of 32.0 atm. the reactor temperature is raised to 235°c and held constant thereafter until the reaction is complete. the propylene conversion at the beginning of the isothermal period is 53.2%. you may assume ideal-gas behavior for this problem, although at the high pressures involved this assumption constitutes an approximation at best. (a) what is the final reactor pressure? (b) what is the percentage conversion of propylene when p 35: 1 atm?

An occluded front moves over the farmland that has been experiencing drought conditions. what change in weather will this front likely bring? a. gray skies, but no rain b. an extended period of rain c. more dry air and sunny skies d. violent, short-lived thunderstorms

Two nitro no2 groups are chemically bonded to a patch of surface. they can't move to another location on the surface, but they can rotate (see sketch at right). it turns out that the amount of rotational kinetic energy each no2 group can have is required to be a multiple of ε, where =ε×1.010−24 j. in other words, each no2 group could have ε of rotational kinetic energy, or 2ε, or 3ε, and so forth — but it cannot have just any old amount of rotational kinetic energy. suppose the total rotational kinetic energy in this system is initially known to be 32ε. then, some heat is removed from the system, and the total rotational kinetic energy falls to 18ε. calculate the change in entropy. round your answer to 3 significant digits, and be sure it has the correct unit symbol.

What type of energy do chemical bonds have? what type of energy is it converted to during chemical reactions? question 15 options: chemical bonds have kinetic energy, which is converted to potential energy during chemical reactions. chemical bonds have electric energy, which is converted to potential energy during chemical reactions. chemical bonds have heat energy, which is converted to kinetic energy during chemical reactions. chemical bonds have potential energy, which is converted to heat energy during chemical reactions.
