A bimolecular heterogeneous catalytic reaction: A(g) +B(g) →P showed that the rate increased at low pAand then the rate decreased at high pA when pB was kept constant. A similar trend was observed withchange in pB at constant pA. What is the rate law?Question 11 options:r=K2KA pA KB pBr= (K2KA PA pB) /(1+ KA pA)r=(K2KA PA KB pB) /( 1+ KA PA + KB pB)2r=(K2KA PA KB pB) /( 1+ KA PA + KB pB) An ideal gas expands in a reversible and adiabatic process. What will happen to the temperature of thegas?Question 12 options:The temperature will riseThe temperature will fallThere will be no change in temperatureThe final temperature will be zero

Ignition wires heat Thermometer Stirrer A bomb calorimeter, or a constant volume calorimeter, is a device often used to determine the heat of combustion of sample fuels and the energy content of foods. In an experiment, a 0.5650 g sample of quinizarin (C14H804) is burned completely in a bomb calorimeter. The calorimeter is surrounded by 1.187×103 g of water. During the combustion the temperature increases from 23.98 to Water 26.55 °C. The heat capacity of water is 4.184 J gloC1. The heat capacity of the calorimeter was determined in a previous experiment to be 770.8 J/°C. Assuming that no energy is lost to the surroundings, calculate the molar heat of combustion of quinizarin based on these data.
