Which answer choices are true statements about the properties of an enclosed gas? select all that apply. if the temperature of a gas remains constant, then increasing its volume will decrease its pressure. if the pressure of a gas remains constant, then increasing its temperature will increase its volume. if the temperature of a gas remains constant, then increasing its volume will increase its pressure. if the volume of a gas remains constant, then increase

sorry, is there a picture? i do not see any arrows.

it provides an alternative energy pathway for the reaction to proceed.

a catalyst is a substance that speeds up the rate of a chemical reaction but is not consumed during the course of the reaction.

catalysts increase the rate of reaction without being used up. they do this by lowering the activation energy needed. with a catalyst, more collisions result in a reaction, so the rate of reaction increases. different reactions need different catalysts.

a catalyst works by providing an alternative reaction pathway to the reaction product. the rate of the reaction is increased as this alternative route has a lower activation energy than the reaction route not mediated by the catalyst.

to this answer it would be edge enhancement
