When concentration of reactant is doubled the rate of reaction becomes 4 times the order of reaction is?

new concentration = 4 * old concentration. Therefore the order is 0.5.

What happens to the rate of reaction if the concentration of B is doubled?

When you double the concentration the rate doubles. The rate is proportional to the square of the concentration of a reactant. When you double the concentration the rate goes up four times.

When concentration of reactants is increased 8 times and rate becomes two times the order of reaction?

When the concentration of a reactant in reaction A→B is increased by 8 times but rate increases only 2 times, the order of the reaction would be 1/n.

Why is doubling the reactant increase the rate of reaction?

Reactant Concentrations Raising the concentrations of reactants makes the reaction happen at a faster rate. For a chemical reaction to occur, there must be a certain number of molecules with energies equal to or greater than the activation energy. By doubling the concentration, the rate of reaction has doubled as well.

What will be the effect on the rate if the concentration of both A and B are tripled?

Rate = k[A][B] and Rate = k[A]2 are both second order reaction. In the first case, A and B are both first order and in the second, A is second order. If a reactant is first order, then when its concentration is doubled, the rate of the reaction doubles; if the concentration is tripled, the rate triples, etc.

Why does increased concentration increase reaction rate?

For a chemical reaction to occur, there must be a certain number of molecules with energies equal to or greater than the activation energy. With an increase in concentration, the number of molecules with the minimum required energy will increase, and therefore the rate of the reaction will increase.

When the concentration of a reactant is increased the?

Increasing the concentration of the reactants will increase the frequency of collisions between the two reactants. When collisions occur, they do not always result in a reaction (atoms misaligned or insufficient energy, etc.). Higher concentrations mean more collisions and more opportunities for reaction.

Why does doubling the concentration double the reaction rate?

Reactant Concentrations With an increase in concentration, the number of molecules with the minimum required energy will increase, and therefore the rate of the reaction will increase. By doubling the concentration, the rate of reaction has doubled as well.
