general questions

Postby Nick Lewis 4F » Mon Mar 09, 2020 2:13 pm

Just one quick question to make sure im studying the right information... In the rate law it is written where a is negative and b and c are positive... is this cause reactant concentration goes down while product concentration goes up?

Yes this is correct, however the rate laws are always positive, that's why the - is included within the reactants.

If the reactants are being consumed, then the rater is negative. Simultaneously, while products are being formed, they are increasing in amount and the rate is positive.

yes; as the reaction occurs, the concentrations of the reactant(s) will decrease as the concentration of the products increase
