How to calculate enthalpy

Posted by Varun Kumar 4 years, 6 months ago

CBSE > Class 11 > Chemistry

1 answers

Rrrrr Rrrrr 4 years, 6 months ago

Use the formula ∆H = m x s x ∆T to solve. Once you have m, the mass of your reactants, s, the specific heat of your product, and ∆T, the temperature change from your reaction, you are prepared to find the enthalpy of reaction. Simply plug your values into the formula ∆H = m x s x ∆T and multiply to solve.
