Which statement best describes why the rate of reaction will increase if you increase the concentration of a solution? a) a higher concentration solution will only react at a higher temperature. b) when the concentration of the solution increases, the amount of the other reactant also increases. c) the higher number of molecules increases the number of collisions that will occur with the reactants. d) if the concentration increases, the number of solution molecules decreases which gives more room for the reaction to occur.

C) The higher number of molecules increases the number of collisions that will occur with the reactants.

Hope this helps!!

i think is conclusions.i think so

(newtons first law)

conservation of momentum law states :

momentum before collision = momentum after collision

momentum p (kg-m/s)= mass * velocity

say moving car=1 000 kg, velocity = 10 m/s then p = 1 000*10= 10 000 kg-m/s

say still car = 2 000 kg, velocity = 0 m/s then p = 2 000* 0 = 0 kg-m/s

total momentum prior to collision = 10 000 + 0 = 10 000 kg-m/s

momentum after collision = 10 000 kg-m/s

mass now = 1 000 kg+2 000 kg = 3 000 kg

10 000 = 3 000 kg* velocity m/s

10 000/3 000 = velocity

3.33 m/s = velocity after collision

an impulse is a force applied over time , momentum is exclusive of external forces and a perfect collision is implied
