A 100.-L flask contains a mixture of methane (CH4) and argon gases at 25 degrees Celsius. The mass of argon present is 228 g and the mole fraction of methane in the mixture is 0.650. Calculate the total kinetic energy of the gaseous mixture.
Assume that 0.406 mol Carbon (g) is placed in a cylinder that is expanding. The barometric pressure on the outside of the cylinder is constant at 1.00 atm and the temperature is 300.0 K.
The activation energy of a certain reaction is 45.4kJ/mol. At 28 degrees celcius, the rate constant is 0.0150s^?1. At what temperature in degrees Celsius would this reaction go twice as fast?
A copper cube measuring 1.60 cm on edge and an aluminum cube measuring 1.61 cm on edge are both heated to 55.3 C and submerged in 100.0 mL of water at 22.1 C.
System were found to be [N2]=[O2]=0.200 M and [NO]=0.500 M. N2(g) + O2(g) 2NO(g) If more NO is added, bringing its concentration to [0.800 M], what will the final concentration of NO be after equilibrium is re-established?
