Q#9.1: How order of reaction is experimentally determined.

Ans. Order of reaction is determined by the following two methods.

1. From Rate Law.

   In this method, the rate of reaction is measured using chemical and physical methods (volumetric, gravimetric, spectrophotometer, pH-meter, conductometric methods). The dependence of the rate of reaction on the concentration of reactants tells us about the order of reaction. For example, a reaction in which the rate of reaction doubles when the concentration of reactants is doubled will be of first order. If the rate increases four times by doubling the concentration, the reaction will be of second order.

2. Ostwald’s Isolation Or Large Excess Method.

   This method is used to determine the order of complicated

1.Write down four ways in which Hitler broke the Treaty of Versailles?He stopped paying WWI reparations.He built up the armed forces.He united Germany and Austria (Anschluss).He invaded Czechoslovakia

Russia of the Tsar: The 20th Century

At the dawn of the 20th century, the Russian Empire was ruled by Tsar Nicholas II. Civil rights were not recognized, and the Tsar maintained his power through a rigid bureaucracy, a powerful army, and the Orthodox Church. The Russian economy was largely agrarian and semi-feudal, worked by a vast peasant majority.

Life Under Tsarist Rule

Peasant living conditions were dire. The agricultural economy, characterized by low production, struggled to feed the entire population. While some capitalist elements had been introduced, industry was largely developed with foreign capital. This industrialization led to the emergence of a new social class: industrial workers.

Utilitarian ethics bases right and wrong on the greatest happiness principle. This principle states that actions are considered moral when they tend to promote happiness and deter its opposite, and immoral when the opposite occurs. This principle was formulated by Jeremy Bentham. Mill claimed that it is demeaning to reduce the meaning of life to pleasure. Utility is defined as pleasure itself and the absence of pain. Happiness is a sign that we are exercising our higher faculties.

When making a moral judgment on an action, utilitarianism thus takes into account not just the quantity but also the quality of the pleasures resulting from it. A pleasure is of higher quality if people would choose it over a different pleasure even if it is accompanied...

Understanding Levers: Simple Machines

What is a Lever?

Levers are simple machines. They are made up of a rigid bar and a point of support, which is also called a fulcrum. They are normally used to exert a large force using only a small force; they are a type of force multiplier.

Key Elements of a Lever

Resistance is the force that must be overcome by the applied force. The point of support, or fulcrum, is the point about which the lever swings. The arms, the force arm and the resistance arm, correspond to the distance between the fulcrum and the applied force or resistance, respectively.

• The force arm is the distance between the fulcrum and the applied force.
• The resistance arm is the distance between the fulcrum and the resistance.
