What is ways that chemical reaction between substance affect chemical bonds

There is a near-infinite list of what might effect reaction rates. Major, common factors are Temperature, Pressure, Solvent Concentration, Solute Concentration, Sterics, Size (Surface area) Catalysts, Concentration and light . The rate of reaction is determined by the Activation Energy

most sediment washes or falls into the river as a result of mass movement and runoff. other sediment eroded from the bottom or sides of the river.
