A gas consists of 20.0 mole% CH4, 30.0% C2H6, and 50.0% C2H4. Ten kilograms of this gas is to be compressed to a pressure of 200 bar at 90°C. Using Kay’s rule, estimate the final volume of the gas.

Take a look at this dandelion. the yellow flower on the right is pollinated and the seeds on the left are transported by

The activation energy for the reaction no2(g)+co2(g)⟶no(g)+co(g) is ea = 300 kj/mol and the change in enthalpy for the reaction is δh = -100 kj/mol . what is the activation energy for the reverse reaction?
