A student is trying to determine the rate law of a chemical reaction. When the initial concentration is varied, the initial reaction rate is always the same. The student concludes that something must be wrong with the chemicals or reaction and decides to increase the temperature. What can you say about this conclusion

Answer:

His conclusion is wrong

Explanation:

Now we must know that there are various rate laws.

In a zero order rate law, the rate of reaction is independent of the initial concentration of reactants. Hence varying the initial concentration of the reactants results in no change of the rate of reaction.

In first and second order rate laws, the rate of reaction varies with the concentration of one or two reactants in either case respectively.

Having said these, the student does not need to change the temperature but rather designate the reaction as zero order. The rate of reaction is independent of the initial concentration of reactants.
