Write the rate law of expression for each of the following equations, and identify the order of reaction: 1.) N2(g) + 2 H2(g) ---- 2 NH3(g) 2.) 2 H2(g) + O2(g) ---- 2 H2O(1) 3.) 3 NO2(g) ---- N2O4(g)

Question

Write the rate law of expression for each of the following equations, and identify the order of reaction: 1.) N2(g) + 2 H2(g) ----> 2 NH3(g) 2.) 2 H2(g) + O2(g) ----> 2 H2O(1) 3.) 3 NO2(g) ----> N2O4(g)

DrBob222 · Answer

Equations 1 and 3 are not balanced. You don't provide any data with which to determine the order of any reaction listed.
For equation 2, 2H2 + O2 --> 2H2O
rate = k(H2)^x(O2)^y where x and y are the orders. This is the rate law but incomplete without the orders.
