What is deltaH in the equation deltaG deltaH TdeltaS?

In the equation (\Delta G = \Delta H - T\Delta S), (\Delta H) represents the change in enthalpy, which reflects the total heat content of a system during a chemical reaction or phase change. It indicates whether the reaction is exothermic (releases heat, (\Delta H < 0)) or endothermic (absorbs heat, (\Delta H > 0)). This term is crucial for understanding the thermodynamic favorability of a process, along with the changes in entropy ((\Delta S)) and temperature (T).


What is the hydrologic equation?

The hydrologic equation, often referred to as the water balance equation, describes the relationship between the input, output, and storage of water within a defined system, such as a watershed. It is expressed as: ( P - E - Q = \Delta S ), where ( P ) is precipitation, ( E ) is evaporation, ( Q ) is runoff, and ( \Delta S ) is the change in storage. This equation highlights how water moves through the environment and helps in understanding and managing water resources.


What variable represents thermal energy in the equation Q equals mcT?

In the equation ( Q = mc\Delta T ), the variable ( Q ) represents thermal energy. Here, ( m ) is the mass of the substance, ( c ) is the specific heat capacity, and ( \Delta T ) is the change in temperature. The equation calculates the amount of thermal energy absorbed or released by a substance when its temperature changes.


Calculate K at 298 K for the following reactions?

To calculate the equilibrium constant ( K ) at 298 K for a given reaction, you'll need the standard Gibbs free energy change (( \Delta G^\circ )) for the reaction, which can be determined from standard enthalpies and entropies of formation. The relationship between ( K ) and ( \Delta G^\circ ) is given by the equation ( \Delta G^\circ = -RT \ln K ), where ( R ) is the gas constant (8.314 J/mol·K) and ( T ) is the temperature in Kelvin. Rearranging this equation allows you to solve for ( K ) using the formula ( K = e^{-\Delta G^\circ / RT} ) once ( \Delta G^\circ ) is known.


What variable represents specific heat in the equation?

In the equation for calculating heat transfer, the variable that represents specific heat is usually denoted by ( c ). Specific heat is defined as the amount of heat required to raise the temperature of one unit mass of a substance by one degree Celsius (or one Kelvin). The equation is often expressed as ( Q = mc\Delta T ), where ( Q ) is the heat added, ( m ) is the mass, and ( \Delta T ) is the change in temperature.
