Chemical Reaction Rates

These flashcards cover the topic of reaction rates in chemical reactions, including how to express the rate for various reactions.

What is the equation for the reaction rate with respect to all species in a reaction A + B -> C + D?

Rate = -d[A]/dt = -d[B]/dt = d[C]/dt = d[D]/dt.

What is the reaction rate expression for the reaction 2 NO(g) + O2(g) -> 2 NO2(g)?

Rate = -1/2 d[NO]/dt = -1/1 d[O2]/dt = 1/2 d[NO2]/dt.

Write the rate equation for the reaction 2 H2(g) + O2(g) -> 2 H2O(g).

Rate = -1/2 d[H2]/dt = -1/1 d[O2]/dt = 1/2 d[H2O]/dt.

How would you express the rate for the reaction N2(g) + 3 H2(g) -> 2 NH3(g)?

Rate = -1/1 d[N2]/dt = -1/3 d[H2]/dt = 1/2 d[NH3]/dt.

What is the rate expression for the decomposition of sulfur dioxide, 2 SO2(g) -> 2 S(s) + O2(g)?

Rate = -1/2 d[SO2]/dt = d[O2]/dt.
