Nitrogen and hydrogen react to form ammonia, like this: N2(g)+3H2(g) — 2 NH3(g) Imagine 61. mmol of NH3 are added to an empty flask, and then answer the following questions. What is the rate of the reverse reaction before any NH3 has been added to the flask? What is the rate of the reverse reaction just after the NH3 has been added to the flask? What is the rate of the reverse reaction at equilibrium? How much NH3 is in the flask at equilibrium? Zero. Greater than zero, but less than the rate of the forward reaction. Greater than zero, and equal to the rate of the forward reaction. Greater than zero, and greater than the rate of the forward reaction. Zero. Greater than zero, but less than the rate of the forward reaction. Greater than zero, and equal to the rate of the forward reaction.

(a) Select all of the correct statements about reaction rates from the choices below. The lower the rate of a reaction the longer it takes to reach completion. Solid catalysts increase reaction rates as their surface areas increase. Catalysts decrease reaction rates. Reaction rate constants decrease with increasing temperature. The higher the rate of a reaction the longer it takes to reach completion. O Reaction rates always increase as masses of solid reactants increase. Reaction rates decrease with increasing temperature.
Burning methane with oxygen is a highly exothermic reaction. Yet a mixture of methane and oxygen can be kept indefinitely without any reaction occurring. How is this possible?
