FREE Expert Solution

Recall that the Rate Law (which considers reactants only) for the reaction: 

2X + Z → products is given by the equation:

Where:

k = rate law constant

a, b = reactant orders

X and Z = reactants

Based on the given experimental data, we can determine the rate constant, k by these steps:

  1. Solve reactant orders: a and b 
  2. Solve for the value of k 
  3. Determine correct units for k
