Why can an increase in temperature lead to more effective collisions between reactant particles and an increase in the rate of a chemical reaction?
(1) the activation energy of the reaction increases.
(2) the activation energy of the reaction decreases.
(3) the number of molecules with sufficient energy to react increases.
(4) the number of molecules with sufficient energy to react decreases.

Achemist is studying the following equilibirum, which has the given equilibrium constant at a certain temperature: 2 no(g) + cl2(g) < => 2 nocl(g) kp = 2 x 10^(-6)he fills a reaction vessel at this temperature with 13. atm of nitrogen monoxide gas and 12. atm of chlorine gas. use this data to answer the questions: a. can you predict the equilibrium pressure of noci, using only the tools available to you within aleks? y/nb. if you said yes, then enter the equilibrium pressure of nocl at right. round your answer to 1 significant digit.
