decreasing the volume

adding N2

increasing the volume

adding H2

2. Consider the following reaction. N₂(g) + 3 H₂(g) ⇋ 2 NH₃(g) The forward reaction is exothermic. Which of the following changes would cause less NH₃ to be produced?

decreasing the temperature

adding H2

increasing the temperature

adding N2 3. What is the effect of a catalyst on a reaction? Drag the terms on the left to the appropriate blanks on the right to complete the sentences. increase decrease The effect of a catalyst is to------ the activation energy for a reaction that will------ the rate of a reaction.

4. Why are catalysts so important to chemistry?

Catalysts are important in chemistry because they make reactions to be exothermic.

Catalysts are important in chemistry because they help to measure the temperature of the reaction.

Catalysts are important in chemistry because many reactions would be too slow to be useful without catalysts.

Catalysts are important in chemistry because they help to calculate the masses of reactants.. 5. Enzymes work in biological systems by _________. increasing the equilibrium constant lowering the activation energy of a reaction decreasing the equilibrium constant increasing the activation energy of a reaction pLEASE help! No need an explanation!..thanks

Increase as increasing the volume 2 N2 og )+ 34₂G) N 13 g) for Enothermic Reactions, conco) & Increasing temp. will shift the equilib towards leften so, why will be prodused less Catalyst :- It decrease ta Rate of > The effect of a catalyst is to decrease the activation energy for a reaction that will increase the rate of a reaction 46 catalyete pre important in theoristry because many reactions would be too stone to be useful without catalyste Catalysts increase rate of reaction ,

s. Enzymes act catalyet in biological A Catalyt decreases the four (Activation Energy) and increase rate de reaction so con el lowering the activation energy of a reaction,
