**Using the given data, calculate the rate constant of this reaction. **
** A+B ----> C+D**

**Trial A(M) B(M) Rate(M/s)**

**1. 0.340 0.200 0.0142**

**2. 0.340 0.520 0.0960**

**3. 0.476 0.200 0.0199**

**k =_____ ?**

**Answer:**

Calculate order of reaction as follows:

Compare powers,

Value of n is 2.

Now, calculate order with respect to reactant A

Compare powers therefore, m is equal to 1.

For calculating the rate constant, order of reactants is needed. Order is calculated by using rate equation.

Calculate rate constant as follows:

Rate constant is calculated by using rate equation. For calculating rate constant, order of reactants is calculated.
