"determine the rate law and the value of k for the following reaction using the data provided. co(g) + cl2(g) → cocl2(g) [co]i (m) [cl2]i (m) initial rate 0.25 0.40 0.696 0.25 0.80 1.97 0.50 0.80 3.94"

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.
