- 1. 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!
- 2. 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
