[Olympiad] For the reaction A + B → C, the rate equation is Rate = k[A]²[B]. If the concentration of A is halved and the concentration of B is doubled, the new rate will be:
Half the original rate
Half the original rate
The same as the original
One-fourth the original rate
📝 Detailed explanation
New Rate = k [1/2 A]² [2 B] = k (1/4)[A]² (2)[B] = (2/4) k[A]²[B] = 1/2 Original Rate.
