The decomposition of dinitrogen pentoxide is described by the following chemical equation 2 N2O5(g)  →  4 NO2(g) + O2(g) If the rate of appearance of O2 is equal to 3.00 mol/min at a particular moment, what is the rate of disappearance of N2O5 at that moment?

What is the overall order of the reaction, rate = k[N2O2][H2]? Enter the number. For example, if the overall order of a reaction is 5, then enter 5.

The combustion of ethylene proceeds by the reaction                C2H4(g) + 3 O2(g)  →  2 CO2(g) + 2 H2O(g) When the rate of disappearance of O2 is 0.28 M s-1, the rate of appearance of CO2 is ________ M s-1.

The first-order decay of radon has a half-life of 3.823 days.  How many grams of radon remain after 7.22 days if the sample initially weighs 250.0 grams?

The first-order reaction, SO2Cl2  →  SO2 + Cl2, has a half-life of 8.75 hours at 593 K. How long will it take for the concentration of SO2Cl2 to fall to 16.5% of its initial value?

Given the following balanced equation, determine the rate of reaction with respect to [O2].  If the rate of O2 loss is 2.64×10-3 M/s, what is the rate of formation of SO3? 2 SO2(g) + O2(g)  →  2 SO3(g)
