Choose all the answers that apply. which of the following will decrease reaction rate? increase pressure decrease temperature increase concentration decrease concentration

The following will decrease reaction rate

The reaction rate (v) shows the change in the concentration of the substance (changes in addition to concentrations for reaction products or changes in concentration reduction for reactants) per unit time.  

Can be formulated:  

Reaction: aA ---> bB  

or  

A = reagent  

B = product  

v = reaction rate  

t = reaction time  

In chemical reactions several factors influence :

The temperature of the reaction that is raised will cause the particles to move more actively so that collisions between particles will become more frequent so that the speed of chemical reactions will be greater

Addition of pressure will increase the concentration because the volume is reduced, a greater concentration will accelerate the reaction

The greater the concentration, the more substances dissolved and involved in the reaction, thereby increasing the speed of the reaction

The mechanical force applied to the solution that reacts will cause more collisions to accelerate the reaction

Addition of a catalyst to accelerate the reaction without reaction with reactant substances

the answer is barium and copper bromide

i think its 100.

hope this !
