Consider the reaction.2x⟶y+zwhen the concentration of x is doubled, the reaction rate increases by a factor of 4. what is the order of the reaction? a.) zero order b.) first-order c.) second order d.) third order
what is the rate equation? a.) rate = k[x]^2 b.) rate= [x]^2 c.) rate= k[x] d.) rate= k[y][z] e.) rate= k x 2[x]
calculate when [x]=0.27 m and the rate of the reaction is 0.0040m/s.

Which element in the third period would you expect to have the larger atomic radius, sodium (na) or sulfur (s)? a. sodium, because it has a higher effective nuclear charge attracting electrons in fewer energy levels. b. sodium, because it has fewer protons attracting electrons in the same energy levels. c. sulfur, because it has more protons attracting electrons in more energy levels. d. sulfur, because it has a higher effective nuclear charge attracting electrons in the same energy levels.
