All the following are ture about reaction rates except Reaction rates can be estimated with the coefficient of the balanced reaction . Because reaction rate does not estimated with the coefficient of the balanced reaction .
A reaction rate can be measured by the change in concentration and time . It is ture because
Reaction rate formula is
Where ∆C = change in concentration
∆t = change in time
Reaction rates change with temperature . It is ture because in general rate of chemical reaction is increased in the rise of temperature .with increasing temperature frequency collision increased and number of chemical specis reaching the energy of activation per unit will also increased . Hence rate of reaction increase . For decreasing the temperature rate also decreases .
Reaction rates change with present of a catalyst . It is ture because a catalyst increases or decreases a reaction rate by lowering or increasing the activation energy .
