Question

Consider the following reaction. 2NO(g) + 2 H2(g) -----> N2(g) + 2H2O(g) a) The rate law for this reaction is first orderis  H2 and second order in NO. Write the ratelaw. b). If the rate constant at 1000 K is (6.0)(104M-2s-1, what is the reaction rate when [NO] =0.035 and [H2] = 0.015 M? c) what is the reaction rate when at 1000K when theconcentration of H2 is 0.010 M?

Explanation / Answer

We Know that :      2NO(g) + 2H2(g) -----> N2 (g) +2H2O(g)        Rate = K [H2 ] [ NO ]2 b.            Reaction Rate = 6.0 x 104M-2s-1 x [ 0.035 M ]2x [ 0.015 M ]                                   = 1.1025 M s-1 c.                ReactionRate = 6.0 x 104M-2s-1 x [ 0.035 M ]2x [ 0.010 M ]                                        = 0.735 M s-1 c.                ReactionRate = 6.0 x 104M-2s-1 x [ 0.035 M ]2x [ 0.010 M ]                                        = 0.735 M s-1
