dependent variable constant

Rates of most chemical reactions increases with temperature because the rate constant 'k' increases with temperature. The temperature dependence of the rate constant is given by the Arrhenius equation, where..

Angle, specific gravity, strain etc., do not have any dimensions and any constant value and hence, are variables..

Consider an example. A person was asked to measure the thickness of a coin. He recorded the following readings: (i) 0.2 cm with ruler (ii) 0.23 cm with vernier (iii) 0.231 cm with micrometer The accuracy of thickness of the coin depended on the instrument used for measuring the thickness..

The amount spent by Chris on a birthday party is a function of number of his friends whom he invited. Which of the following is a dependent variable? => Chris′s age or number of members in Chris′s family or number of friends Chris invited or amount spent by Chris on ..

The concentration of CuSO 4 decreases while that of ZnSO 4 increases. As electrode potential depends upon concentration, a stage comes where both the electrode potentials are equal. Current stops flowing and the cell is said to have attained equilibriu..

Consider the homogeneous equations a 1 x + b 1 y + c 1 z = 0 a 2 x + b 2 y + c 2 z = 0 a 3 x + b 3 y + c 3 z = 0 The homogenous system of equations is always consistent because x = 0, y = 0, z = 0 satisfies all the equations in the system. This solution is called the trivial solution. then the s..

> will be dominant species in the system at equilibrium. For the reaction at 298 K, Large value of K, indicates that at equilibrium, a major portion of nitrogen and hydrogen (mixed in the molar ratio 1:3) will be converted into ammonia. Industrially ammonia is manufactured at a high pressure of 152..

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..

In mathematical sense, equilibrium constant is not a constant. It is called constant because at a fixed temperature and pressure, the value of the equilibrium constant for a reaction is constant. The unit of equilibrium constant (K) of a ..

The mass of the oscillating particle The force constant of the spring (or any other agency) which supplies the restoring force. The above equation tells us that period is independent of the amplitude. Such a motion is said to be isochronous..
