Which of the following choices is a pair of like terms? => 5 xp , 8 p 2 or 4 m , -4 m or 4 t , 2 s or 4 m 3 , -4 m..

Working rules for finding the greatest term: Step 1: In (a + b) n , the constants a and b must be positive. Step 2: Write T r+1 and T r and find the value of T r+1 /T r . Step 3: Simplify the inequality (T r+1 /T r ) greater than or equal to 1 an..

Every molecule in a gas is in a state of constant straight-line motion. Molecules very frequently collide with one another, and against the sides of the container (Fig. 15.4). It is assumed that the molecules do not lose energy during these collisions. Hence the sum total amount of the ki..

Rules for Writing Equilibrium Constant Expressions - Expression for the equilibrium constant of a reaction is written in the form of a ratio. The numerator consists of the molar concentration (or partial pressure) terms of the products each raised to a power equal to i..

Consider a reversible reaction expressed by the following general equation: where A and B are two substances which react to form new substances C and D and C and D react under the same conditions forming the original substances A and B. Let us assume that the concentrations of these four substances..

The law of mass action correlates the rate of a chemical reaction and the concentration of the reactants. C.M. Guldberg and P. Waage (1864-67) suggested this relationship. This law states that, at a constant temperature and pressure, the rate of a chemical reaction is directly proportio..

The value of the equilibrium constant of a reaction is the same, at constant 'T' and 'P'. However, if either temperature 'T' or pressure 'P' or both are changed, the value of the equilibrium constant may also change. For example, the value of K p (equilibrium co..

Some main characteristics of equilibrium constant are described below: The value of the equilibrium constant of a reaction is the same, at constant 'T' and 'P'. However, if either temperature 'T' or pressure 'P' or both are changed, the value of the equilibrium co..

> The above results can be summarized as follows: When a reaction proceeds, the number of moles converting from reactants to the products may or may not change. The change in the number of moles (except for pure liquids, solids and solvent in excess) converting from reactants to the products is cal..

What is the number of terms in the product (8 + 7 )(8 - 7 ) , after like terms have been combined? => 2 or 0 or 3 or 1..
