Deviation will occur for volume assumption at A. Low Pressure
B. High Pressure
C. Constant Pressure
D. 1 atm

B. is it right?​

because of all the things that happen around the us, many people get into arguments which sadly could get physical, but we should actually make a change for that.

option c: 1605.1 kj

the balanced chemical reaction for combustion of methane is as follows:

here, enthalpy formation of is -74.7 kj/mol, 0 kj/mol, -393.5 kj/mol and -241.82 kj/mol respectively.

the heat released or can be calculated as follow:

putting the values,

thus, heat released by combustion of 1 mol of methane is 802.54 kj/mol. thus, for 2 mol, heat released will be:

therefore, heat released by the combustion of 2 mol of methane is 1605.1 kj.
