I have the following code in datalore
#reaction rates rate = kplus1*concentration_co2 - kminus1*concentration_h2co3 dmoles_co2_dt = (flow_co2_0 - flow_co2-rate*reactor_volume) dmoles_h2co3_dt = flow_h2co3_0-flow_h2co3+rate*reactor_volume
on the second line, datalore throws the error “Unresolved reference ‘rate’”. As can be seen, rate is clearly defined the line immediately preceding the line where the error is thrown. All other terms are defined previously in the code.
