Chemistry module 3

• how do you work out activation energy from gradient of a rate graph?


  gradient = -Ea/R

  so x by -R to get Ea in Joules

  -then divide by 1000 to get KJ
• how do you convert dm3 to m3?

  divide by 1000
• how do you convert cm3 to m3


  divide by 1,000,000 / x10-6
• how do you convert kPa to Pa?

  x 1000
• how do you convert MPa to Pa?


  x 1,000,000 / X10^6
