The initial rate of production of NO2 for this reaction is approximately:
O a. 7.4 x 10-4 mol/L min
O b. 3.2 x 10-4 mol/L min
O c. 1.24 x 10-2 mol/L min
O d. 1.6 x 10-4 mol/L'min
e.
none of these

the temperature of the gas, in k, not celsius.

the enthalpy of formation of water is given as -285.8kj/mol, which states that the enthalpy of formation is negative.

negative enthalpy of formation indicates that the heat is released during the reaction process. the heat is released from reaction to the surroundings the enthalpy is expressed with a negative sign with the energy given out in the reaction process.

the formation of water takes place by giving out heat which is -285.8 kj/mol.

the pseudoscience are like beliefs, theories, or like practices that are considered scientific

the answer is symmetrical : )
