# Problem: Consider the hypothetical reaction 2 A + B → 2 C + D. The following two-step mechanism is proposed for the reaction:Step 1: A + B → C + XStep 2: A + X → C + DX is an unstable intermediate.What is the predicted rate law expression if Step 1 is rate determining?

###### FREE Expert Solution

For this problem, we are being asked to write the rate law expression if Step 1 is rate-determining?

When a reaction mechanism is given, the rate law can be determined using the slow step in the reaction mechanism.

• Rate law only involves the reactants
• The coefficients of the reactants in the slow step are the order of the reaction with respect to that reactant
• Rate Law has a general form of:
