Problem: Experiments were conducted to study the rate of the reaction represented by this equation.[2] 2 NO(g) + 2 H2(g) ⟶ N2(g) + 2 H2O(g) Initial concentrations and rates of reaction are given here.Consider the following questions:(d) For experiment 2, calculate the concentration of NO remaining when exactly one-half of the original amount of H2 had been consumed.

FREE Expert Solution

We’re being asked to calculate the concentration of NO remaining when exactly one-half of the original amount of H2 had been consumed. 


Recall that the rate law only focuses on the reactant concentrations and has a general form of:

rate law=kAxBy

k = rate constant
A & B = reactants
x & y = reactant orders


We are going to do the following steps to solve this problem:

Step 1: Calculate the order of the reaction with respect to NO

Step 2: Calculate the order of the reaction with respect to H2

Step 3: Calculate the value of the rate constant

Step 4: Calculate the concentration of NO remaining
