The ammonia and methane in the early atmosphere were removed when they reacted with oxygen. Add the missing numbers to complete
the equations for these processes.

CH4 + _O2 → CO2 + _H2O

_ NH3 + _O2 → _N2 +_ H2O

Consider the reaction of a(g) + b(g) + c(g) => d(g) for which the following data were obtained: experiment initial [a], mol/l initial [b], mol/l initial [c], mol/l initial rate, mol/l. s 1 0.0500 0.0500 0.0100 6.25 x 10^-3 2 0.100 0.0500 0.0100 2.50 x 10^-2 3 0.100 0.100 0.0100 1.00 x 10^-1 4 0.0500 0.0500 0.0200 6.25 x 10^-3 what is the rate law for the reaction?

Ab c or d ? i’m not sure what the answer is
