How does an increase in temperature affect rate of reaction? Explain this effect in terms of the collision theory of the reaction rate.
Can a reaction mechanism ever be proven correct? Can it be proven incorrect?
If a textbook defined a catalyst as "a substance that increases the rate of a reaction," would that definition be adequate?
The reaction NO(g) + O,(g) — NO,(g) + 0(g) plays a role in the formation of nitrogen dioxide in automobile engines. Suppose that a series of experiments measured the rate of this reaction at 500 K and produced the following data; [NO] (mol L ’) [OJ (mol L 1) Rate = -A[NO]/Af (mol L_1 s-1) 0.002 0.005 8.0 X 10"'7 0.002 0.010 1.6 X 10-'6 0.006 0.005 2.4 X IO-'6 Derive a rate law for the reaction and determine the value of the rate constant.
