Help 4.For each of the following reactions, indicate whether you would expect the entropy of the
system to increase or decrease, and explain why. If you cannot tell just by inspecting the
equation, explain why.
(a) CH3OH() → CH3OH(g)
(b) N204(g) + 2NO2(g)
(c) 2KCIO3(s) → 2KCI(s) + 302
(d) 2NH3(g) + H2SO4(aq) →(NH4)2SO4(aq)

If the particles in a sample of matter have an orderly arrangement and move only in place, the sample is a

For the reaction, 4 a(g) + 3 b(g) => 2 c(g), the following data were obtained at constant temperature. experiment initial[a],mol/l initial [b],mol/l initial rate,m/min 1 0.200 0.150 5.00 2 0.400 0.150 10.0 3 0.200 0.300 10.0 4 0.400 0.300 20.0 which of the following is the correct rate law for the reaction? 1. rate = k[a]2[b]2 2. rate = k[a][b] 3. rate = k[a]2[b] 4. rate = k[a][b]2

Voltaic cells produce a positive overall charge. what does this indicate? a. the reaction is likely to be endothermic. b. the reaction is spontaneous. c. the reaction is not likely to occur. d. the reaction is not spontaneous.
