Chemical reaction rates are proportional to a rate constant, k, which changes with temperature according to the Arrhenius equati

Vanyuwa [196]

Answer:

see answer below

Explanation:

the equation is given by

k=ko* e^(-Q/RT)

then replacing the known values

k=1200 min⁻¹ e^[-8000 cal/mole/ (1.987 cal/mole K *T)]

then replacing values of T every 50 K from 100 to 500 K we get the series of values

$\left[\begin{array}{ccc}T&k\\100&3.924*10^{-15} min ^{-1} \\150&2.643*10^{-9} min ^{-1} \\200&2.17*10^{-6} min ^{-1} \\250&1.216*10^{-4} min ^{-1} \\300&1.781*10^{-3} min ^{-1} \\350&0.012 min ^{-1} \\400&0.051 min ^{-1} \\450&0.156 min ^{-1} \\500&0.382 min ^{-1} \end{array}\right]$

//The first layout we use will be 1 row with three columns

setLayout(new GridLayout(1,3));

//initialize all the components

//we check which value has been tampered with and base our conversion off this

//because of this it is important that the user clears, or else it will do inch conversion

if(inches != 0.00)

{

cms = inches * 2.54;

meters = cms / 100;

yards = inches / 36;

cm_tf.setText(df.format(cms));

}

else if(meters != 0.00)

{

}

{

inches = cms / 2.54;

yards = inches / 36;

meters = cms / 100;

meters_tf.setText(df.format(meters));

inch_tf.setText(df.format(inches));

yards_tf.setText(df.format(yards));

}

Explanation:

Inside the action performed method, pass the strings in text box.
check if the value has been modified then do the relevant conversions inside the conditional statement.
When the user clears, it will not do to the inch conversion.
