To analyze the given chemical reaction, we need to break down the equation and evaluate each statement based on the stoichiometry of the reaction. The equation provided is:

C6H12O6 + 12 H2SO4 → 6 CO2 + 12 SO2 + 18 H2O

Let's go through each conclusion one by one to determine their validity.

A) Mass ratio of C6H12O6 and H2SO4 present is 1:12

This statement is incorrect. The mass ratio depends on the molar masses of the compounds. The molar mass of glucose (C6H12O6) is approximately 180 g/mol, and that of sulfuric acid (H2SO4) is about 98 g/mol. Therefore, the mass ratio is:

• Mass of C6H12O6 = 180 g
• Mass of 12 H2SO4 = 12 × 98 g = 1176 g
• Mass ratio = 180 g : 1176 g = 1 : 6.53 (approximately)

So, this conclusion is incorrect.

B) Mole ratio of C6H12O6 and H2SO4 present is 1:12

This statement is correct. The coefficients in the balanced equation indicate that for every 1 mole of glucose, there are 12 moles of sulfuric acid. Thus, the mole ratio is indeed 1:12.

C) Mass ratio of C6H12O6 and H2SO4 reacted is 1:12

D) Mole ratio of H2SO4 and CO2 in reaction mixture is 2:1

This conclusion is incorrect. From the balanced equation, we see that for every 12 moles of H2SO4, 6 moles of CO2 are produced. Therefore, the mole ratio of H2SO4 to CO2 is 12:6, which simplifies to 2:1. This statement is correct.

E) Mass ratio of H2SO4 and CO2 in reaction mixture is 2:1

This statement is incorrect. The mass ratio cannot be determined solely from the mole ratio without considering the molar masses. The molar mass of CO2 is about 44 g/mol, so the mass ratio would need to be calculated based on the actual masses of H2SO4 and CO2 produced.

F) Mole ratio of H2O and C6H12O6 present in reaction mixture is 18:1

This conclusion is correct. The balanced equation shows that for every 1 mole of C6H12O6, 18 moles of H2O are produced. Therefore, the mole ratio is indeed 18:1.

G) Mole ratio of SO2 and CO2 formed is 2:1

This statement is correct. The balanced equation indicates that for every 6 moles of CO2 produced, 12 moles of SO2 are produced, which simplifies to a ratio of 2:1.

H) Sum of number of moles of H2SO4 and SO2 in the reaction mixture is always constant

This conclusion is incorrect. The number of moles of H2SO4 decreases as it reacts, while the number of moles of SO2 increases. Therefore, the sum is not constant throughout the reaction.

I) Sum of number of moles of C6H12O6 and CO2 present in the reaction mixture is always constant

This statement is also incorrect. Similar to the previous conclusion, the number of moles of C6H12O6 decreases as it reacts, while the number of moles of CO2 increases. Thus, their sum is not constant.

Summary of Conclusions

Based on the analysis:

• B) Correct
• D) Correct
• F) Correct
• G) Correct

In total, there are four correct conclusions (B, D, F, G) based on the stoichiometry of the reaction.
