Question

What element is being reduced in the following redox reaction? H_2O_2(l) + ClO_2(aq) + O_2 (g) C N O H Cl Which one of the following is a correct representation of a beta particle?^0_1e^2_4beta^0_-1e^1_0beta^4_2e Which of the following processes have a delta S > 0? Na_2CO_3(s) +H_2O(g) + CO_2(g) rightarrow 2 N_aHCO_3(s) CH_3OH(I) rightarrow CH_3OH(s) N_2(g) + 3 H_2(g) rightarrow 2 NH_3(g) CH_4(g) + H_2O(g) rightarrow CO(g) + 2 H_2(g) All of the above processes have a delta S > 0. The standard cell potential (E degree cell) for the reaction below is +0.63 V. The cell potential for this reaction is _____ V when [Zn^2+] = 3.5 M and [Pb^2+] = 2.0 times 10^-4 M.

Explanation / Answer

16)
I am sorry to say that E can't be the answer
Correct answer is D

Let me explain,

for A:
number of gaseous molecules of reactant side is more.
so S < 0

for B:
reactant is liquid and product a solid. Liquid has more entropy than solid.
so S < 0

for C:
number of gaseous molecules of reactant side is more.
so S < 0

for D:
number of gaseous molecules of product side is more.
so S > 0

Hence the answer should be D
