B) convection
C) insulation
D) none of these

charging by contactExplanation:

Hope it helps

A) Charging by contact

Explanation:

Transfer of heat by direct contact, Heat energy is conducted from the hotter medium to the cooler medium

answer: the value of enthalpy change will be -152.80 kj.

solution:

pressure = 1atm , temperature = = 298 k

given that pressure and temperature are same in both gases , the number of moles of both gases can be determined by the ideal gas equation.

according to reaction 3 moles no are reacting with 1 mol of ,then 0.49 mol of no will react with moles of ozone that is 0.16 moles of ozone. since, no is limiting reagent and is an excessive reagent.

enthalpy change for the reaction between the given volumes of the gases is :
