Respuesta :
The reaction could speed up by increasing the concentration of HBr and by heating the reaction mixture.
By increasing the concentration of HBr
According to the rate law , the rate of reaction is directly proportional to the concentration of reactants.
A -----B
R = k[A]
where, k is the proportionality constant.
If we increase the concentration of reactant the rate of reaction increase and by decreasing the concentration of reactant , the rate of reaction decreases
By heating the reaction mixture.
As we increase the temperature the rate of reaction increase. By increasing the temperature by 10°C , the rate of reaction become double. This is termed as temperature coefficient.
This is because after increasing the temperature, the kinetic energy of the molecules increases, More molecules collide. Therefore, number of collision increases which results in the increases in the rate of reaction.
By decreasing the temperature, the rate of reaction decrease. So we can say that rate of reaction is directly proportional to the temperature.
Thus, we concluded that the rate of reaction is directly proportional to both concentration of reactant and temperature.
