For a hypothetical reaction ` A + B to ` products
The rate law is `, R = R[A]^(@) [B]` , The order of reaction is

Options

A. 1
B. 2
C. 1.5
D. Zero

Answer

To determine the order of the reaction given the rate law, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Rate Law**:
The rate law given is \( R = k[A]^0[B]^1 \).

2. **Understand the Components**:
- \( k \) is the rate constant.
- \( [A] \) is the concentration of reactant A.
- \( [B] \) is the concentration of reactant B.
- The exponents (0 and 1) indicate the order with respect to each reactant.

3. **Determine the Order with Respect to Each Reactant**:
- The order with respect to reactant A is 0 (since the exponent is 0).
- The order with respect to reactant B is 1 (since the exponent is 1).

4. **Calculate the Overall Order of the Reaction**:
The overall order of the reaction is the sum of the individual orders:
\[ \text{Overall order} = \text{Order with respect to A} + \text{Order with respect to B} = 0 + 1 = 1 \]

5. **Conclusion**:
The overall order of the reaction is 1.

### Final Answer:
The order of the reaction is **1**.
