3 CH3NH2 + 11 HNO3 ---> 3 CO2 + 13 H2O + 14 NO

RATE OF DISAPPEARANCE OF NITRIC ACID IS 20M/min.

what is the rate of reaction? at what rate is the concentration of carbon dioxide changing?

To find the rate of reaction, we can use the stoichiometry of the balanced chemical equation.

From the balanced equation, we can see that the stoichiometric ratio between HNO3 and NO is 11:14.

Given the rate of disappearance of nitric acid (HNO3) is 20 M/min, we can calculate the rate of reaction as follows:

Rate of reaction = (Rate of disappearance of HNO3) / (Stoichiometric coefficient of HNO3 in the balanced equation)
= 20 M/min / 11
≈ 1.82 M/min

Hence, the rate of reaction is approximately 1.82 M/min.

To determine the rate at which the concentration of carbon dioxide (CO2) is changing, we need to consider the stoichiometric ratio between HNO3 and CO2, which is 11:3.

Rate of change of concentration of CO2 = (Rate of disappearance of HNO3) / (Stoichiometric coefficient of HNO3 in the balanced equation) * (Stoichiometric coefficient of CO2 in the balanced equation)
= 20 M/min / 11 * 3
≈ 0.545 M/min

Therefore, the rate at which the concentration of carbon dioxide is changing is approximately 0.545 M/min.

To determine the rate of reaction and the rate at which the concentration of carbon dioxide (CO2) is changing, we need to consider the balanced chemical equation and the stoichiometry of the reaction.

From the balanced chemical equation:
3 CH3NH2 + 11 HNO3 ---> 3 CO2 + 13 H2O + 14 NO

We can see that 11 moles of HNO3 are consumed for every 3 moles of CO2 produced. Therefore, the rate of reaction and the rate of change in CO2 concentration are related by the stoichiometric coefficients.

Given that the rate of disappearance of nitric acid (HNO3) is 20 M/min, we can calculate the rate of reaction and the rate of change in CO2 concentration as follows:

Rate of reaction = (Rate of disappearance of HNO3) / Stoichiometric coefficient of HNO3
Rate of reaction = 20 M/min / 11 = 1.82 M/min

Since the stoichiometric coefficient of CO2 is 3, the rate of change in CO2 concentration will be three times the rate of reaction:

Rate of change in CO2 concentration = 3 * Rate of reaction
Rate of change in CO2 concentration = 3 * 1.82 M/min = 5.46 M/min

Therefore, the rate of reaction is 1.82 M/min and the rate at which the concentration of carbon dioxide is changing is 5.46 M/min.
