enthalapy#!#FLOT

When 1 mol of real gas absorbes 100 kJ heat at constant pressure of 1 bar, it’s volume changes from 2 L to 2.5 L. What is the enthalapy for the gas?

Assertion: The enthalapy of reaction remains constant in the presence of a catalyst. Reason: A catalyst participating in the reaction, forms different activated complex and lowers down the activation energy but the difference in energy of reactants lead to product formation.

What is the change in enthalapy (kcal) when 1 mole of ideal monoatomic gas is expended reversibly and adibatically from initial volume of 1 L and initial temperature 300 K to final volume of 8 L :

A certain mass of a gas is expended from [2 L, 20 atm, 300 K] to [5 L, 10 atm, 320 K] against a constant external pressure of 5 atm. If heat capacity of the gas is 100J//^(@)C then enthalapy change of the process will be : [1 atm lit. = 100 J]

The combustion of 1.22 g benzoic acid (M=122) in a bomb calorimeter at 300 K caused a temperature rise of 3 K, While combustion of 0.88 g ethyl ethanote (M=88) caused a temperature rise of 2 K. Calculate the enthalapy change of combustion of CH_(3)COOC_(2)H_(5)(l) at 300 K. Given : Internal energy change of combustion for benzoic acid =-300kJ mol^(-1) at 300 K and R=8.3 JK^(-1)mol^(-1)
