# Fill in the following equations- Rate of reaction for A - 2B Rate law.docx

Fill in the following equations:
Rate of reaction for A ? 2B
Rate law for a A + b B ? c C + d D
Arrhenius equation
Solution
1)Rate of reaction for A ? 2B
is rate= k[A] x .2[B] y
k=rate costant, x= order of recation with respect to A, y= order of recation with respect to B
[A],[B]=concentration in mol per dm 3
2) Rate law for aA + bB ? cC + dD
is rate law= ka[A] p .b[B] q .c[C] r ,d[D] s
p,q,r,s order of recation with respect to A,B,C,D
3) arrhenious equation
k=Ae -E A /RT
Temperature, T
To fit into the equation, this has to be meaured in kelvin.
The gas constant, R
This is a constant which comes from an equation, pV=nRT, which relates the pressure, volume and temperature of a particular number of moles of gas. It turns up in all sorts of unlikely places!
Activation energy, E A
This is the minimum energy needed for the reaction to occur. To fit this into the equation, it has to be expressed in joules per mole - not in kJ mol -1
