u no decrease in volume equals to increase in pressure(boyle's law)...xo there is no change. . if pressure is increase on such a reaction were both reactant and product are equal in numba of moles
the number if mole of the reactants is equal to the number of mole of the product so pressure has no effect
applying boyl'les law. an increase in pressure decreases the volume. of a given gas.
Decrease in pressure is synonymous to an increase in pressure of a gaseous reaction system. It is only option A in which an increase in pressure does not have an effect on the reaction system.
