Under certain conditions the rate of this reaction is zero order in hydrogen iodide with a rate constant of 0.0030 M-s¹: 2 HI(g) → H₂(g) + 1₂ (g) Suppose a 350. mL flask is charged under these conditions with 350. mmol of hydrogen iodide. How much is left 80. s later? You may assume no other reaction is important. Be sure your answer has a unit symbol, if necessary, and round it to the correct number of significant digits. 0 По olo

Why do reactions generally occur faster at high temperatures based on the collision theory? Choose all that apply  High temperatures mean: - lower the activation energy requirement  - high kinetic energy= greater number of collisions per time unit  - increase solubility  - high internal energy= more effective collisions by energy levels (activation energy)

Question:Consider a hypothetical chemical reaction that involves the conversion of reactants A and B into products C and D. The reaction is known to be highly exothermic and occurs in a closed system at constant temperature and pressure. Based on this information, answer the following question: Why does the rate of reaction decrease over time, even though the reaction is exothermic?

A certain catalyzed reaction is known to have an activation energy . Furthermore, the rate of this reaction is measured at and found to be . Use this information to answer the questions in the table below. Suppose the concentrations of all reactants is kept the same, but the temperature is raised by from to . The rate will choose one How will the rate of the reaction change? Suppose the concentrations of all reactants is kept the same, but the catalyst is removed, which has the effect of raising the activation energy by , from to . The rate will

Pls help on bith of these questions. Define these pls.

For a reaction which is first order with respect to one reactant, plotting result in a straight line. versus time will one over reactant concentration O reactant concentration O None of the other four answers is correct. O In of reactant concentration one over In of reactant concentration

What are the units of the rate constant for a third order reaction? Can you explain with equations..?

How does the increase in the concentration of one reactant affect the rate of reaction if all other terms are unchanged? (Please show all information this question)
