Suppose the reaction between nitric oxide and bromine proceeds by the following mechanism:
NO(g) + Br2(g) → NOBr2 (g)
NOBr2(g) + NO(g)→2 NOBr

Suppose also k1 ≫ k2. That is, the first step is much faster than the second.

a. Write the balanced chemical equation for the overall chemical reaction.
b. Write the experimentally-observable rate law for the overall chemical reaction.
c. Express the rate constant k for the overall chemical reaction in terms of k1, k2, and (if necessary) the rate constants k-1 and k-2 for the reverse of the two elementary reactions in the mechanism.

What are the variables in gay-lussac’s law? pressure and volume pressure, temperature, and volume pressure and temperature volume, temperature, and moles of gas

Nebulae are enormous clouds in outer space. they are made mostly of hydrogen gas, helium gas, and dust. some nebulae glow brightly, while others do not. the stars that people see are huge, bright balls of glowing gas. they are made mostly of hydrogen and helium. which statement correctly describes other ways in which nebulae and stars are different? a. stars can form inside a nebula but a nebula can never be produced by any star. b. a star always has a higher density than a nebula. c. stars can never form inside a nebula but a nebula can be produced by any star. d. a nebula always has a higher density than a star.
