The reaction between  nitrogen  and  oxygen  is given below: 2N 2 (g)  +  O 2 (g)   2N 2 O(g)   We therefore know that which of the following reactions can also occur ? 2NO 2 (g)   N 2 (g)  +  2O 2 (g) 2N 2 O(g)   2N 2 (g)  +  O 2 (g) N 2 (g)  +  2O 2 (g)   2NO 2 (g)   None of the Above Feedback: The principle of Microscopic Reversibility states: Any ELEMENTARY chemical reaction can occur in both the forward and reverse directions.  Since all chemical reactions proceed as a series of elementary steps, all reactions are, in principle, reversible.  If the forward reaction occurs: 2N 2 (g)  +  O 2 (g)   2N 2 O(g)   We also know that the reverse reaction (in theory) also occurs: 2N 2 O(g)   2N 2 (g)  +  O 2 (g) The reaction between  ammonia  and  nitrous oxide  is given below: 2NH 3 (g)  +  3N 2 O(g)   4N 2 (g)  +  3H 2 O(g) We therefore know that which of the following reactions can also occur ? 4NH 3 (g)  +  6NO(g)   5N 2 (g)  +  6H 2 O(l) 5N 2 (g)  +  6H 2 O(l)   4NH 3 (g)  +  6NO(g) 4N 2 (g)  +  3H 2 O(g)   2NH 3 (g)  +  3N 2 O(g) None of the Above Feedback: The principle of Microscopic Reversibility states: Any ELEMENTARY chemical reaction can occur in both the forward and reverse directions.  Since all chemical reactions proceed as a series of elementary steps, all reactions are, in principle, reversible.  If the forward reaction occurs: 2NH 3 (g)  +  3N 2 O(g)   4N 2 (g)  +  3H 2 O(g) We also know that the reverse reaction (in theory) also occurs: 4N 2 (g)  +  3H 2 O(g)   2NH 3 (g)  +  3N 2 O(g) Write the equilibrium constant expression, K c , for the following reaction:  If either the numerator or denominator is 1, please enter 1
