Rate Laws (Section)
Consider the following reaction:
2 NO(g) + 2 H2(g)→N2(g) + 2 H20(g)
(a) The rate law for this reaction is first order in H2 and second order in NO. Write the rate law.
(b) If the rate constant for this reaction at 1000 K is 6.0 x 104 M-2 s-1. what is the reaction rate when [NO] = 0.035 M and [H2] = 0.015 M? (c) What is the reaction rate at 1000 K when the concentration of NO is increased to 0.10 M, while the concentration of H2 is 0.010 M? (d) What is the reaction rate at 1000 K if [NO] is decreased to 0.010 M and [H2] is increased to 0.030 M?
General Chemistry 1311 HONORS September 11, 2016 Dr. Lumpkin Set 1 Theory vs. Laws ● A theory is falsifiable ● A law is an observation which remains the same under certain conditions History of Atomic Theory ● Democritus first theorized that matter is composed of small, indivisible particles called atoms ● John Dalton popularized the idea with his atomic theory (the following bullets are quoted from Dr. Lumpkin’s notes) ○ Each element is composed of tiny, indivisible particles called atoms ○ All atoms of a given element have the same mass and physical properties ○ The atoms of one element are different from those of any other element ○ Ato
